Evidence for a new state decaying into two
photons in the search for the standard model Higgs boson in pp collisions
/CMS Collaboration
A search for a Higgs boson decaying into two photons is described.
The analysis is performed using datasets recorded by the CMS experiment at the
LHC from pp collisions at a centre-of-mass energies of 7~TeV and 8~TeV.
The datasets correspond
to an integrated luminosity of 5.1 and 5.3~fb$^{-1}$, respectively.
Limits are set on the cross section of the standard model Higgs boson
decaying to two photons.
An excess of events above the expected standard model background is
observed for a Higgs boson mass hypothesis of 125~GeV, with a local significance of 4.1$\sigma$. The global significance of observing an excess with a local
significance $\geq$4.1$\sigma$ anywhere in
the search range 110--150~GeV is estimated to be 3.2$\sigma$. [...]

Studies of $\Lambda^0_{\mathrm{b}} \rightarrow \mathrm{J}/\psi \Lambda$ production in $pp$ collisions at $\sqrt{s}$ = 7 TeV
/LHCb Collaboration
The $\Lambda^0_{\mathrm{b}} \rightarrow \mathrm{J}/\psi \Lambda$ production cross-section is measured with the LHCb detector in inelastic $pp$ collisions at a centre-of-mass energy of $\sqrt{s}$ = 7 TeV. Using 36.4 pb$^{-1}$ of data recorded in 2010, the cross-section for the region with rapidity 2.2 < $y$ < 4.5 and transverse momentum $p_T < 13.0 \rm{GeV}/c$ is found to be $\sigma (pp \rightarrow \Lambda^0_{\mathrm{b} } X) \cal{B} (\Lambda^0_{\mathrm{b} } \rightarrow \mathrm{J}/ \psi \Lambda) = 4.19 \pm 0.61 \mathrm{(stat)} \pm 0.37 \mathrm{(syst)}$ nb for the baryon and $\sigma(pp \to \overline{\Lambda}^0_{\mathrm{b}} X) \cal{B} (\overline{\Lambda}^0_{\mathrm{b}} \rightarrow \mathrm{J }/\psi \Lambda) = 2.63 \pm 0.48 \mathrm{(stat)} \pm 0.27 \mathrm{(syst)}$ nb for the antibaryon decay..

Characteristics of multi-particle production in pp collisions at sqrt(s) = 7 TeV are studied as a function of charged-particle multiplicity (N_ch), where charged particles are divided into two distinct classes: those belonging to jets, and those belonging to the underlying event (UE). Charged particles are measured within pseudorapidity |eta| < 2.4 and transverse momenta above p_T = 0.25 GeV/c, and charged-particle jets are reconstructed above p_T = 5 GeV/c with track only information.

Phenomenological MSSM interpretation of the CMS 2011 5fb-1 results
/CMS Collaboration
We interpret within the phenomenological MSSM (pMSSM) results obtained
by CMS using a $pp$ data set collected in 2011 at 7~TeV, corresponding
to an integrated luminosity of 5~fb$^{-1}$.
The pMSSM is a 19-parameter realization of the MSSM defined at the SUSY
scale, that captures most of the features of the general R-parity
conserving weak-scale MSSM.
A global Bayesian analysis is performed that yields posterior
probability densities of model parameters, masses and observables. We
provide conclusions that are more generic, and therefore more robust,
than those derived in more constrained setups, including simplified
models and models that impose particular SUSY breaking schemes, such
as the CMSSM.
%Our results also comprise We also study implications for the MSSM Higgs sector,
as well as for dark matter searches. [...]

The CERN PS, which started in 1959, and the Brookhaven AGS in 1960, represented an advance by a factor of more than five in the energy of proton accelerators, from the 5 GeV of the Berkeley Bevatron to about 30 GeV. These accelerators made possible the large progress in our understanding of particles and their interactions over the next two decades, culminating in the electroweak and QCD gauge theories..

Measurement of inelastic, single- and double-diffraction cross sections in proton-proton collisions at the LHC with ALICE
/ ALICE Collaboration
Measurements of cross sections of inelastic and diffractive processes in proton--proton collisions at LHC energies were carried out with the ALICE detector. The fractions of diffractive processes in inelastic collisions were determined from a study of gaps in charged particle pseudorapidity distributions: for single diffraction (diffractive mass $M_X < 200$ GeV/$c^2$) $\sigma_{\rm SD}/\sigma_{\rm INEL} = 0.21 \pm 0.03, 0.20^{+0.07}_{-0.08}$, and $0.20^{+0.04}_{-0.07}$, respectively at centre-of-mass energies $\sqrt{s} = 0.9, 2.76$, and 7 TeV; for double diffraction (for a pseudorapidity gap $\Delta\eta > 3$) $\sigma_{\rm DD}/\sigma_{\rm INEL} = 0.11 \pm 0.03, 0.12 \pm 0.05$, and $0.12^{+0.05}_{-0.04}$, respectively at $\sqrt{s} = 0.9, 2.76$, and 7 TeV.

Measurement with the ATLAS detector of multi-particle azimuthal correlations in p+Pb collisions at $\sqrt{s_{NN}}$=5.02 TeV
/ ATLAS Collaboration
In order to study further the long-range correlations (“ridge”) observed recently in p+Pb collisions at $\sqrt{s_{NN}}$ = 5:02 TeV, the second-order azimuthal anisotropy parameter of charged particles, $v_2$, has been measured with the cumulant method using the ATLAS detector at the LHC. In a data sample corresponding to an integrated luminosity of approximately 1 microbarn-1, the parameter $v_2$ has been obtained using two- and four-particle cumulants over the pseudorapidity range |$\eta$| < 2.5.

LHCb observed evidence for a very rare decay of a neutral $B_S$ meson into a pair of muons[1]. The probability that the background could produce such an excess or larger is mere 5.3 x $10^{-4}$. This corresponds to signal significance of 3.5 standard deviations in the combined 1.0fb$^{-1}$ of 2011 (√s=7TeV) and 1.11f$^{-1}$ of 2012 (√s=8TeV) data.

LHCb is preparing the upgrade which is scheduled to be installed in 2018/19. The Scintillating Fibre (SciFi) Tracker will be designed to replace the current tracking system downstream of the magnet, required to run at an increased luminosity of 1 - 2 10$^{33}$ cm$^{-2}$s$^{-1}$ and to collect a total of 50fb$^{-1}$ of data. The readout of the detector will be at 40MHz, applying a full software based trigger for every single bunch crossing. The SciFi Tracker consists of 12 planes covering a total surface of 350 m2. Modules are based on 2.5 m long multilayer ribbons made of 250 um diameter scintillating fibres as the active medium and signal transport. Silicon photomultiplier (SiPM) arrays with 128 channels at a width of 250 um are used for the readout. The signals from the SiPMS are digitized on an ASIC chip before reconstructing the track hit position within an FPGA on the front-end board. Several challenges facing this detector and the significant progress over the last year will be presented regarding the precision construction of the large active detector components, the radiation hardness of the scintillating fibers and the SiPMs, the high density readout electronics, and the necessary cooling system

The ATLAS Distributed Computing infrastructure has evolved after the first period of LHC data taking in order to cope with the challenges of the upcoming LHC Run2. An increased data rate and computing demands of the Monte-Carlo simulation, as well as new approaches to ATLAS analysis, dictated a more dynamic workload management system (ProdSys2) and data management system (Rucio), overcoming the boundaries imposed by the design of the old computing model.

Phenomenological MSSM interpretation of the CMS 7 and 8 TeV results
/CMS Collaboration
We interpret within the phenomenological MSSM (pMSSM) results from searches for new physics performed by CMS in $pp$ data sets collected at 7~TeV and 8~TeV, corresponding to integrated luminosities of 5~fb$^{-1}$ and 19.5~fb$^{-1}$, respectively.
The pMSSM is a 19-parameter realization of the MSSM, defined at the SUSY
scale, that captures most of the features of the general R-parity conserving weak-scale MSSM. It allows us to draw conclusions that are more generic than , and complimentary to,
those derived in more constrained models, including simplified
models and those that impose particular SUSY breaking schemes, such
as the CMSSM.
We perform a global Bayesian analysis on a data set,
which in addition to CMS search results, includes data from pre-CMS and indirect measurements.
We study posterior probability densities of model parameters, masses and observables and study implications for the MSSM Higgs sector and dark matter searches.
Our study provides a coherent global picture of how the current CMS
searches constrain supersymmetry in general..

Two identical sets of calorimeters are located on both sides with respect to the beam Interaction Point (IP), 112.5 m away from it. Each set of detectors consists of a neutron (ZN) and a proton (ZP) Zero Degree Calorimeter (ZDC), positioned on remotely controlled platforms. The ZN is placed at zero degree with respect to the LHC beam axis, between the two beam pipes, while the ZP is positioned externally to the outgoing beam pipe. The spectator protons are separated from the ion beams by means of the dipole magnet D1.

The Transition Radiation Detector (TRD) is the main electron detector in ALICE. In conduction with the TPC and the ITS, it provides the necessary electron identification capability to study: - Production of light and heavy vector mesons as well as the continuum in the di-electron channel, - Semi leptonic decays of hadrons with open charm and open beauty via the single-electron channel using the displaced vertex information provided by the ITS, - Correlated DD and BB pairs via coincidences of electrons in the central barrel and muons in the forward muon arm, - Jets with high Pτ tracks in one single TRD stack.
The Time Projection Chamber (TPC) is the main device in the ALICE 'central barrel' for the tracking and identification (PID) of charged particles. It has to cope with unprecedented densities of charges particles.

In Theory: Are theoreticians just football fanatics?
/ by Harriet Jarlett ; Harriet Kim Jarlett (ed.)
Listening to a theoretician talk about their field can be a bit like listening to a football fan talking about the team they support.
Whether they fell in love with string theory because of the excitement of something new, like a World Cup win, or doggedly pursued supersymmetry despite several losses, theoreticians will stand by their field while they're working on it, rarely moving into other theories.
This almost obsessive pursuit of one field means, like a supporter who can reel off the goal scorer for every game, theoreticians focus on knowing the ins and outs of their own field.
“The level of complexity of the different branches of theoretical physics is such that nobody can be an expert in everything,” says Gian Giudice, the head of the theory department, who works on particle physics and cosmology.
Gian Giudice is the head of CERN's Theory Department. He believes that the way science develops often follows paths that are much less logical and rational than most people think [...]

LHC optics scenarios enlarging kinematic region of diffractive protons measured by ALFA detector
/ Jirakova, Katerina (Palacky University, RCPTM); Sykora, Tomas (Charles University in Prague, Faculty of Mathematics and Physics)
The purpose of this note is to show that by using a proper combination of dedicated magnets for vertical manipulation with the beam, called vertical correctors, it is possible to enlarge kinematically interesting region of diffractive protons with $p_{T}$ $\simeq$ $0$. We consider methods involving three, four-point bumps and beam crossing, and determine strengths of correctors fields taking in account technical limitations of magnets. [...]

/ Ruf, Thomas (CERN) ; Perazzini, Stefano (CERN) ; Van Herwijnen, Eric (CERN)
This note presents the measurement of the relative branching ratio between the doubly Cabibbo-suppressed $\Lambda_c^+\to p K^+\pi^-$ and the Cabibbo-favoured $\Lambda_c^+\to p\pi^+ K^-$ decays, using a sample of pp collisions corresponding to an integrated luminosity of approximately 300pb$^{-1}$, collected with the LHCb detector at a centre-of-mass energy of 13 TeV during 2015. A clear signal of $xx \pm yy$ events is observed, compared to $(xx \pm yy) \times 10^{-6}$ Cabbibo favoured decays, resulting in a branching ratio of $(xx \pm yy\,{\rm (stat.)} \pm zz\,{\rm (syst.)} \pm vv\,{\rm (pdg)}) \times 10^{-5})$ [...]

Abstract: With the increase in energy of the Large Hadron Collider to a centre-of-mass energy of 13 TeV for Run 2, events with dense environments, such as in the cores of high-energy jets, became a focus for new physics searches as well as measurements of the Standard Model. These environments are characterized by charged-particle separations of the order of the tracking detectors sensor granularity. [...]

Search for dark matter at $\sqrt{s}=13$ TeV in final states containing an energetic photon and large missing transverse momentum with the ATLAS detector
/ ATLAS Collaboration
Results of a search for physics beyond the Standard Model in events containing an energetic photon and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported. As the number of events observed in data, corresponding to an integrated luminosity of 36.1 $\textrm fb^{-1}$ of proton-proton collisions at a centre-of-mass energy of 13 TeV, is in agreement with the Standard Model expectations, exclusion limits in models where dark-matter candidates are pair-produced are determined.

Measurements of the electroweak production of a $W$ boson in association with two jets at high dijet invariant mass are performed using $\sqrt{s} = 7$ and $8$ TeV proton--proton collision data produced by the Large Hadron Collider, corresponding respectively to 4.7 and 20.2 fb$^{-1}$ of integrated luminosity collected by the ATLAS detector. The measurements are sensitive to the production of a $W$ boson via a triple-gauge-boson vertex and include both the fiducial and differential cross sections of the electroweak process..

Monte Carlo Methods for Radiation Transport : Fundamentals and Advanced Topics
This book is a guide to the use of Monte Carlo techniques in radiation transport. This topic is of great interest for medical physicists. Praised as a "gold standard" for accurate radiotherapy dose calculations, Monte Carlo has stimulated a high level of research activity that has produced thousands of papers within the past few years. The book is designed primarily to address the needs of an academically inclined medical physicist who wishes to learn the technique, as well as experienced users of standard Monte Carlo codes who wish to gain insight into the underlying mathematics of Monte Carlo algorithms.

The rejection of forward jets originating from additional proton--proton interactions (pile-up) is crucial for a variety of physics analyses at the LHC, including Standard Model measurements and searches for physics beyond the Standard Model. The identification of such jets is challenging due to the lack of track and vertex information in the pseudorapidity range $|\eta|>2.5$. [...]

The topics covered included: electromagnetism, relativity and the basics of beam dynamics, different injection and extraction schemes, special magnetic and electrostatic elements for the case of lepton and hadron beams, the technical layout of state-of-the-art kicker and septa designs, and the special features of resonant extraction, as used in machines for medical applications.
For the case studies, students were divided into small groups to complete a number of design tasks. This not only provided an opportunity for applying the theoretical knowledge to real-life problems, but also an opportunity to discuss the topic in detail with the lecturers and tutors [...]

Object based Missing Transverse Momentum Significance in the ATLAS Detector
/ Schaefer, Douglas (University of Chicago, Enrico Fermi Institute); Portillo Quintero, Dilia Maria (Laboratoire de Physique Nucleaire et de Hautes Energies (LPNHE), UPMC, Universite Paris-Diderot, CNRS/IN2P3); Francavilla, Paolo (INFN Pisa and Universita' di Pisa, Dipartimento di Fisica); Macdonald, Calum Michael (University of Sheffield); Petrov, Mariyan (University of Oxford, Particle Physics); Tolley, Emma (Ohio State University)
Missing transverse momentum, $E_{\rm T}^{\rm miss}$, is commonly used to study the production of weakly interacting particles. The missing transverse momentum significance, $\mathcal{S}$, helps to separate events in which the reconstructed ${E_{\rm T}^{\rm miss}}$ originates from weakly interacting particles, from those in which ${E_{\rm T}^{\rm miss}}$ is consistent with contributions coming from particle measurement, resolutions and inefficiencies.

A search for the exclusive decays of the Higgs and $Z$ bosons to a $J/\psi$ or $\Upsilon(nS)$ ($n=1,2,3$) meson and a photon is performed with a $pp$ collision data sample corresponding to an integrated luminosity of $36.1\,$fb$^{-1}$ collected at $\sqrt{s}=13$ TeV with the ATLAS detector at the CERN Large Hadron Collider. These decays have been suggested as a probe of the Higgs boson couplings to charm and bottom quarks. [...]

However there is always performance penalty with virtualization, especially for short jobs which are always the case for volunteer computing tasks, the overhead of virtualization becomes a big portion in the wall time, hence it leads to low CPU efficiency of the jobs.

Performance study of HL-LHC ATLAS RPC prototype
A new type of RPC chamber prototype, consisting of a triplet of 50100 cm2 RPCs, having 1mm gas gap, 1.2mm electrodes and new high sensitivity front end electronics, has been
designed for the HL-LHC ATLAS upgrade program. Beam test of this prototype chamber was performed in GIF++ using 100 GeV muons and a 14 TBq 137Cs gamma source to simulate the HL-LHC environment. The amplified analog signals of the chamber have been read out by 32 channels of high speed digitizer, permitting to study in details the various aspects of the detector physics in different condition of gamma background and field applied in the gas. Analysis methods and results of these data will be presented, illustrating in details the most relevant features of this new detector: ~98% efficiency, 400 ps ~ 500 ps time resolution and ~0.1 cm spatial resolution, cross talk in between the singlets and cluster size.

- ATLAS Collaboration.
A search for quantum black holes in electron-jet and muon-jet invariant mass spectra is performed with $139\,$fb$^{-1}$ of data collected by the ATLAS detector in proton-proton collisions at $\sqrt{s} = 13$ TeV at the Large Hadron Collider.The observed invariant mass spectrum of lepton-jet pairs is consistent with Standard Model expectations. Upper limits are set at 95% confidence level on the production cross sections time branching fractions for quantum black holes decaying to a lepton and a quark in a search region with invariant mass above 2.0 TeV.

Ultra-peripheral heavy-ion collisions at the LHC
/ Contreras, J G (Prague, Tech. U.) ; Tapia Takaki, J D (Kansas U.)
The LHC is not only the most powerful collider for proton–proton and heavy-ion collisions, but also for photon–photon and photon–hadron (γp and γPb) interactions, offering a unique opportunity to study fundamental aspects of QED and QCD via photon-induced processes. The protons and ions which are accelerated by the LHC themselves carry an electromagnetic field, which can be viewed as a source of photons.That is, a photon generated by one of these hadrons can interact with another photon (or with a hadron) producing a wide variety of particles..

Search for a Higgs boson decaying into two photons in the CMS detector
/CMS Collaboration
This note describes the search for a Higgs boson decaying into
diphotons in pp collisions at the LHC at a center-of-mass
energy of 7~TeV.
Data-driven methods are used to evaluate the reconstruction and selection
performance for the signal, and the background is evaluated from a fit
to the data. The analysis is performed on a dataset corresponding to 1.66~fb$^{-1}$ of data
recorded in 2011 by the CMS experiment.
Limits are set on the cross section of a Standard Model Higgs boson
decaying to 2 photons, and on the cross section of a fermiophobic Higgs boson
decaying to 2 photons.
The expected exclusion limit at 95\% CL is between 2.7 and 4.7 times
the Standard Model cross section, and the observed limit fluctuates between
about 1.3 and 8 times the Standard Model cross section.
For the fermiophobic model, the expected exclusion limit at 95\% CL
covers the mass range between 110-116.5~GeV$/c^{2}$, while the
data excludes only the mass range 110-112~GeV$/c^{2}$..

Reconstruction and identification of boosted di-$\tau$ systems in a search for Higgs boson pairs using 13 TeV proton$-$proton collision data in ATLAS

In this paper, a new technique for reconstructing and identifying hadronically decaying $\tau^+\tau^-$ pairs with a large Lorentz boost, referred to as the di-$\tau$ tagger, is developed and used for the first time in the ATLAS experiment at the Large Hadron Collider. A benchmark di-$\tau$ tagging selection is employed in the search for resonant Higgs boson pair production, where one Higgs boson decays into a boosted $b\bar{b}$ pair and the other into a boosted $\tau^+\tau^-$ pair, with two hadronically decaying $\tau$-leptons in the final state.

Performance of the missing transverse momentum triggers for the ATLAS detector during Run-2 data taking

The factor of four increase in the LHC luminosity, from $0.5\times 10^{34}\,\textrm{cm}^{-2}\textrm{s}^{-1}$ to $2.0\times 10^{34}\textrm{cm}^{-2}\textrm{s}^{-1}$, and the corresponding increase in pile-up collisions during the 2015-2018 data-taking period, presented a challenge for ATLAS to trigger on missing transverse momentum. The output data rate at fixed threshold typically increases exponentially with the number of pile-up collisions, so the legacy algorithms from previous LHC data-taking periods had to be tuned and new approaches developed to maintain the high trigger efficiency achieved in earlier operations.

The data sets used in this search were collected using a dedicated dimuon trigger stream with low transverse momentum thresholds, recorded at high rate by retaining a reduced amount of trigger-level information, in order to explore otherwise inaccessible phase space at low dimuon mass and non-zero displacement from the interaction point.

After the hangover: QuarkDB and the new namespace
/ Bitzes, Georgios (speaker) (CERN)
In this talk we give a brief overview of the successful migration to the new namespace. Practically all EOS instances at CERN are currently on QuarkDB, the new namespace is officially *boring technology*, and *MGM boot time* a distant memory.
We will also discuss future plans and ideas to further improve scalability and performance of the namespace in particular with respect to locking, planned end-of-support for in-memory legacy namespace, and all miscellaneous namespace-related news..

The first disk-based custodial storage for the ALICE experiment
/ Ahn, Sang Un (speaker) (Korea Institute of Science & Technology Information (KR))
We proposed a disk-based custodial storage as an alternative to tape for the ALICE experiment at CERN to preserve its raw data.
The proposed storage system relies on RAIN layout -- the implementation of erasure coding in the EOS storage suite, which is developed by CERN -- for data protection and takes full advantage of high-density JBOD enclosures to maximize storage capacity as well as to achieve cost-effectiveness comparable to tape.
The system we present provides 18 PB of total raw capacity from the 18 set of high-density JBOD enclosures attached to 9 EOS front-end servers.
In order to balance between usable space and data protection, the system will stripe a file into 16 chunks on the 4-parity enabled RAIN layout configured on top of 18 containerized EOS FSTs.
Although the reduction rate of available space increases up to $33.3\%$ with this layout, the estimated annual data loss rate drops down to $8.6 \times 10^{-5}\%$.
In this paper, we discuss the system architecture of the disk-based custodial storage, 4-parity RAIN layout, deployment automation, and the integration to the ALICE experiment in detail..

Cryogenic safety organisation at CERN
/ Arregui Rementeria, Carlos (speaker) (CERN)
With Safety being a top priority of CERN’s general policy, the Organisation defines and implements a Policy that sets out the general principles governing Safety at CERN. To the end of the attainment of said Safety objectives, the organic units (owners/users of the equipment) are assigned the responsibility for the implementation of the CERN Safety Policy at all levels of the organization, whereas the Health and Safety and Environmental Protection Unit (HSE) has the role of providing assistance for the implementation of the Safety Policy, and a monitoring role related to the implementation of continuous improvement of Safety, compliance with the Safety Rules and the handling of emergency situations.
This talk will elaborate on the roles, responsibilities and organisational structure of the different stakeholders within the Organization with regards to Safety, and in particular to cryogenic safety. [...]

Precise Determination of the Z Resonance Parameters at LEP : Zedometry
/ OPAL Collaboration
This final analysis of hadronic and leptonic cross-sections and of leptonic forward-backward asymmetries in e+e- collisions with the OPAL detector makes use of the full LEP1 data sample comprising 161 pb^-1 of integrated luminosity and 4.5 x 10^6 selected Z decays. An interpretation of the data in terms of contributions from pure Z exchange and from Z-gamma interference allows the parameters of the Z resonance to be determined in a model-independent way. [...]

Search for top squarks in final states with many light flavor jets and 0, 1, or 2 leptons in proton-proton collisions at sqrt(s) = 13 TeV
- CMS Collaboration.
Several new physics models including versions of supersymmetry (SUSY) characterized by R-parity violation (RPV) or with additional hidden sectors predict the production of events with top quarks, low missing transverse momentum, and many additional quarks or gluons. The results of a search for top squarks decaying to two top quarks and six additional light-flavor quarks or gluons are reported. [...]

Search for the lepton-flavor violating decay $B_s^0\to \phi \mu^\pm \tau^\mp$
/ LHCb Collaboration
A search for the lepton-flavor violating decays $B^0_s\to\phi\mu^\pm\tau^\mp$ is presented, using a sample of proton-proton collisions at center-of-mass energies of 7, 8, and 13 TeV, collected with the LHCb detector and corresponding to a total integrated luminosity of $9\,\text{fb}^{-1}$. The $\tau$ leptons are selected using decays with three charged pions. [...]

$b \to c l \bar{\nu}$ decays at LHCb
/ Chen, Chen (Marseille, CPPM)
This report introduces two recent measurements of semileptonic $b$-hadron decays at the LHCb experiment, including a test of Lepton Flavour Universality (LFU) using $\bar{B}^0 \to D^{(*)+} l^- \bar{\nu}_l$ decays where $l\in\{\mu,\tau\}$, and a study of the $D^{*+}$ longitudinal polarisation in the $\bar{B}^0 \to D^{*+} \tau^- \bar{\nu}_\tau$ decay.

Dear Authors and the ARC Members, Congratulations on an interesting paper on systematic-aware neural networks. It is rewarding to see that limited authorship papers by the CMS authors [5,29] are now being extended to become a full CMS paper. Well done! Please, find my detailed comments on the CWR version of the paper below, split into the physics and style categories.

Hi, I’m revising this draft for the statistics committee. I also include some non-statistic related comments, since I also read it as part of the institutional review and missed the internal deadline. I have first a general comment. I understand that the goal of the paper is to explain the technique and proof it works in a real analysis but wonder if you really need to give so many physics details. I don’t think that matters much to a reader [...]

Dear colleagues, Thank you for putting together this publication that summarizes an interesting and fundamental effort to incorporate systematics in the way we perform ML trainings. As is usually the case, in what follows we will concentrate on suggestions for clarifying some important aspects of the work, as well as for improving the clarity of presentation and the overall impact of our publication (Type B comments) and placing slightly less attention to Type A comments. We hope you find our [...]

; 11 Oct 2024
dear authors, this is the institutional review from ROME group. I must confess that it was really difficult to review this paper, given its very technical content. It seems strange to us to publish this paper as a CMS paper; this work shows a new version (new NN training) of an already published analysis. In our opinion a limited authorship paper (on open data?) would be more appropriate. However, please find below our comments to v17 of the paper. [...]

Dear Authors, Congratulations on the production of this technology and the presentation of your findings in this document. I attach below the comments on behalf of the University of California San Diego. Type B 6: Suggest to define H to be “Higgs boson”. Later on line 9 you seem to be using H in this way already. First equation: I don’t understand the use of “… k_l! … k_L!”. Could this not be condensed to simply “… k_L!” [...]

Dear authors, congratulations on a very nicely written paper. I have compiled a few comments from my colleagues at Santander. They are almost exclusively of type A. It is likely that one of our colleagues might send comments of type B on Monday, Oct. 14. Type A comments: Line 34. however --> however, Line 34. an NN --> a NN Line 136. There is no erroneous identification of jets as electrons? Lines 140-141. Keep "POWHEG 2" in the same line. [...]

Dear authors, Please find below simple comments from non-experts who do not know much details about the neural network approach. - would it be it possible to present a simple case as an illustration of the approach? For example, one measures some quantity which is distributed according to Poisson distribution with n_tot = n_b + n_s Your goal is to determine the number of signal events n_s, and you expect the number of the background events n_b with some [...]

Submitting comments from Lucien Cremaldi representing U Mississippi. Many thanks for reading and commenting on this paper. Best, Markus This is a very nice work from the team. They verified a more sophisticated NN training method which incorporated systematic uncertainties in to a new NN Model. As a non-expert with some NN experience I can only make cursory comments. I decided not to read Ref [1,4,5]. The paper should be self-sufficient on basic matters. The paper is well [...]

CMS Institutional Review from PISA We think that the paper is well written, and the potential applications are significant. When explaining its results, it obviously relies a lot on the methodological references and on the chosen benchmark analysis, but this is clearly necessary in order to avoid explaining everything from scratch. We have a few comments and questions regarding the data processing choices and some of the results obtained (type B comments), as well as minor comments on the text [...]

RAL Institutional Review of MLG-23-001 General comments on the paper Congratulations to the authors on this interesting paper. This is a really good idea for tackling our data processing challenges. The success of this method is heavily dependent on machine learning algorithms. Seeing the throughput gains in this paper from offloading the ML algorithms to GPUs (which is 9% of the processing time), I would emphasize more the potential future benefits, as one would anticipate a steady growth of ML [...]
