 ALPINIST: Axion-Like Particles In Numerous Interactions Simulated and Tabulated / Jerhot, Jan (Louvain U., CP3) ; Döbrich, Babette (CERN) ; Ertas, Fatih (Aachen, Tech. Hochsch.) ; Kahlhoefer, Felix (Aachen, Tech. Hochsch.) ; Spadaro, Tommaso (Frascati) Proton beam dump experiments are among the most promising strategies to search for light and feebly interacting states such as axion-like particles (ALPs).

 Azimuthal Asymmetries in Unpolarised Semi-Inclusive DIS at COMPASS / Matousek, Jan (Charles U.) In semi-inclusive deep inelastic scattering (SIDIS) the non-zero transverse momentum of partons $k_\mathrm{T}$ induces azimuthal dependence of the cross-section. [...] arXiv:2201.05205. - 5 p. Fulltext

 Pair-production of the charged IDM scalars at high energy CLIC / Klamka, Jan Franciszek (University of Warsaw (PL)) ; Zarnecki, Aleksander (University of Warsaw (PL)) The Inert Doublet Model (IDM) is a simple extension of the Standard Model, introducing an additional Higgs doublet that brings in four new scalar particles. The lightest of the IDM scalars is stable and is a good candidate for a dark matter particle. [...] CLICdp-Pub-2022-001.- Geneva : CERN, 2022 - 17. Fulltext: PDF;

 Flavour anomalies in supersymmetric scenarioswith non-minimal flavour violation / Boussejra, M.A. ; Mahmoudi, F. ; Uhlrich, G. Motivated by tensions between experimental measurements and SM predictions in $b\to s \ell^+\ell^-$ transitions, we present the first study of non-minimal flavour violating MSSM scenarios contributing to the relevant Wilson coefficients to address the observed anomalies using SuperIso and MARTY We calculate the full one-loop analytical contributions of the general MSSM to Wilson coefficients relevant for flavor anomalies, together with the anomalous muon magnetic dipole moment $(g-2)_\mu$.

 Search for long-lived heavy neutral leptons with displaced vertices in proton-proton collisions at $\sqrt{s} =$ 13 TeV / CMS Collaboration A search for heavy neutral leptons (HNLs), the right-handed Dirac or Majorana neutrinos, is performed in final states with three charged leptons (electrons or muons) using proton-proton collision data collected by the CMS experiment at $\sqrt{s} =$ 13 TeV at the CERN LHC.

 Precision QCD Measurements from CMS / Cerci, Salim (Istanbul U.) /CMS Collaboration Recent measurements of jet events are presented which test QCD with unprecedented precision. The measurements are based on Run 2 data collected with the CMS detector at the LHC. [...] CMS-CR-2021-131.- Geneva : CERN, 2021 - 5 p.

 Status and Commissioning of the CMS Experiment / Buchmuller, Oliver (Imperial Coll., London) ; Schilling, Frank-Peter (KIT, Karlsruhe, EKP) After a brief overview of the Compact Muon Solenoid (CMS) experiment, the status of construction and installation is described in the first part of the note. The second part of the document is devoted to a discussion of the general commissioning strategy of the CMS experiment, with a particular emphasis on trigger, calibration and alignment.

 The upgrade of the CMS pixel detector / Favaro, Carlotta (IRFU, Saclay) /CMS Collaboration The CMS inner pixel detector system is planned to be upgraded during the first phase of LHC upgrades. The plans call for an ultra low mass system with four barrel layers with three disks on either end. [...] CMS-CR-2010-286.- Geneva : CERN, 2010 - 6 p.

 Xrootd Monitoring for the CMS experiment / Tadel, Matevz (UC, San Diego) /CMS Collaboration During spring and summer 2011 CMS deployed Xrootd front-end servers on all US T1 and T2 sites. This allows for remote access to all experiment data and is used for user-analysis, visualization, running of jobs at T2s and T3s when data is not available at local sites, and as a fail-over mechanism for data-access in CMSSW jobs. Monitoring of Xrootd infrastructure is implemented on three levels. [...] CMS-CR-2012-086.- Geneva : CERN, 2012 - 10 p.

 Stitched Together Transitioning CMS to a Hierarchical Threaded Framework / Jones, Christopher Duncan (Fermilab) ; Sexton-Kennedy, Elizabeth (Fermilab) /CMS Collaboration Modern computing hardware is transitioning from using a single high frequency complicated computing core to many lower frequency simpler cores. As part of that transition, hardware manufacturers are urging developers to exploit concurrency in their programs via operating system threads. [...] CMS-CR-2013-393.- Geneva : CERN, 2013 - p.
