Measurement of indirect CP asymmetries in $D^0 \to K^-K^+$ and $D^0 \to \pi^-\pi^+$ decays
/ LHCb Collaboration
Time-dependent $CP$ asymmetries in the decay rates of the singly Cabibbo-suppressed decays $D^0\rightarrow K^-K^+$ and $D^0\rightarrow \pi^-\pi^+$ are measured in $pp$ collision data corresponding to an integrated luminosity of 3.0 fb$^{-1}$ collected by the LHCb experiment. The $D^0$ mesons are produced in semileptonic $b$-hadron decays, where the charge of the accompanying muon is used to determine the initial state as $D^0$ or $\bar{D}^0$. [...]

Production of W-bosons in p-Pb collisions measured with ALICE at the LHC
/ Buthelezi, Edith Zinhle (iThemba LABS)
/for the ALICE Collaboration
W bosons are produced in hard scattering processes of partons in collisions of hadrons and they do not interact strongly with the medium produced in high-energy heavy-ion collisions. Therefore, in p-Pb collisions the measurement of W-boson yields represents a standard candle to check the validity of binary-collision scaling and can provide important constraints on the parton distribution functions, which can be modified in nuclei with respect to protons or neutrons.

In the Wordwide LHC Computing Grid (WLCG) project the Tier centres are of paramount importance for storing and accessing experiment data and for running the batch jobs necessary for experiment production activities. Although Tier2 sites provide a significant fraction of the resources a non-availability of resources at the Tier0 or the Tier1s can seriously harm not only WLCG Operations but also the experiments' workflow and the storage of LHC data which are very expensive to reproduce. This is why availability requirements for these sites are high and committed in the WLCG Memorandum of Understanding (MoU). In this talk we describe the workflow of GGUS ALARMs, the only 24/7 mechanism available to LHC experiment experts for reporting to the Tier0 or the Tier1s problems with their Critical Services. Conclusions and experience gained from the detailed drills performed in each such ALARM for the last 4 years are explained and the shift with time of Type of Problems met. The physical infrastructure put in place to achieve GGUS 24/7 availability are summarised.

CLIC (Compact Linear Collider) has tight requirements regarding pre-alignment of beam related components: 10 µm accuracy over a sliding window of 200 m along the 20 km of linac. To perform such an alignment, a new system is proposed combining laser beam as straight line reference and camera/shutter assemblies as sensors. The poster describes the alignment system and shows results regarding laser pointing stability with respect to time, shutter type, distance and environment. These results give a frame for future building and calibrating of sensors.

Neutrinos (1/3)
/ Gonzalez-Garcia, Concepcion (speaker) (ICREA, Barcelona, Spain and YITP, Stony Brook, USA)
The neutrino, the lightest and most weakly interacting particle of the Standard Model has revealed itself as the messenger of very exciting news in particle physics: there is Physics Beyond the Standard Model. All this thanks to the quantum-mechanical phenomenon of flavour oscillations which is intrinsically connected to the question of neutrino mass and which has been observed in neutrinos produced in natural sources, like the Sun and the Earth's atmosphere, as well as with human made neutrino beams at accelerator and reactors.

Today, science, technology and innovation are among the most powerful forces driving social change and development. However, what is the actual role that a fundamental science laboratory like CERN can have when it comes to designing creative strategies to strengthen public goods in society?
With a view to contribute to the realisation of the 2030 Agenda for Sustainable Development, which was approved in September by the United Nations Member States, the United Nations Office at Geneva (UNOG) hosted a one-day symposium organised in collaboration with CERN and with the support of Switzerland and France, in their capacity as CERN host states.

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.

Measurement of $CP$ asymmetries in $D^{\pm}\rightarrow \eta^{\prime} \pi^{\pm}$ and $D_s^{\pm}\rightarrow \eta^{\prime} \pi^{\pm}$ decays
/ LHCb Collaboration
A search for $CP$ violation in $D^{\pm}\rightarrow \eta^{\prime} \pi^{\pm}$ and $D^{\pm}_{s}\rightarrow \eta^{\prime} \pi^{\pm}$ decays is performed using proton-proton collision data, corresponding to an integrated luminosity of $3$ fb$^{-1}$, recorded by the LHCb experiment at centre-of-mass energies of $7$ and $8$ TeV. The measured $CP$-violating charge asymmetries are $A_{CP}(D^{\pm} \rightarrow \eta^{\prime} \pi^{\pm})=(-0.61\pm 0.72 \pm 0.53 \pm 0.12)\%$ and $A_{CP}(D^{\pm}_{s}\rightarrow \eta^{\prime} \pi^{\pm})=(-0.82\pm 0.36 \pm 0.22 \pm 0.27)\%$, where the first uncertainties are statistical, the second systematic, and the third are the uncertainties on the $A_{CP}(D^{\pm} \rightarrow K^0_S \pi^{\pm})$ and $A_{CP}(D^{\pm}_{s}\rightarrow \phi \pi^{\pm})$ measurements used for calibration.

Observation of $B_{c}^{+} \rightarrow D^{0} K^{+}$ decays
/ LHCb Collaboration
Using proton-proton collision data corresponding to an integrated luminosity of 3.0 fb$^{-1}$, recorded by the LHCb detector at centre-of-mass energies of 7 and 8 TeV, the $B_{c}^{+} \rightarrow D^{0} K^{+}$ decay is observed with a statistical significance of 5.1 standard deviations. By normalising to $B^{+} \rightarrow \bar{D}^{0} \pi^{+}$ decays, a measurement of the branching fraction multiplied by the production rates for $B_{c}^{+}$ relative to $B^{+}$ mesons in the LHCb acceptance is obtained, R_{D^{0} K} = \frac{f_{c}}{f_{u}}\times\mathcal{B}(B_{c}^{+} \rightarrow D^{0} K^{+}) = (9.3\,^{+2.8}_{-2.5} \pm 0.6) \times 10^{-7}\,where the first uncertainty is statistical and the second is systematic.

Muon momentum measurement in ICARUS-T600 LAr-TPC via multiple scattering in few-GeV range

A sample of ~1000 stopping muons produced by charged current interactions of CNGS {\nu}{\mu} in the surrounding rock at the INFN Gran Sasso underground Laboratory provides an ideal benchmark in the few-GeV range since their momentum can be directly and independently obtained by the calorimetric measurement.

Since the rank-two system is dual to a free rank-one higher-dimensional system, that effectively describes conformal fields in six space-time dimensions, the constructed system can be interpreted as describing a mixture between linear conformal fields in four and six dimensions.

In this note we investigate Gra{\ss}mannian formulas for form factors of the chiral part of the stress-tensor multiplet in $\mathcal{N}=4$ superconformal Yang-Mills theory. We present an all-$n$ contour for the $G(3,n+2)$ Gra{\ss}mannian integral of NMHV form factors derived from on-shell diagrams and the BCFW recursion relation. [...]

The pseudorapidity distribution of charged hadrons in pp collisions at $\sqrt{s} =$ 13 TeV is measured using a data sample obtained with the CMS detector, operated at zero magnetic field, at the CERN LHC. The yield of primary charged long-lived hadrons produced in inelastic pp collisions is determined in the central region of the CMS pixel detector ($|\eta|$ < 2) using both hit pairs and reconstructed tracks.

In this letter, the production of deuterons and anti-deuterons in pp collisions at $\sqrt{s} = 7$ TeV is studied as a function of the charged-particle multiplicity density at mid-rapidity with the ALICE detector at the LHC. Production yields are measured at mid-rapidity in five multiplicity classes and as a function of the deuteron transverse momentum ($p_{\rm{T}}$). [...]

TELEMAKO PROJECT. TEMPORARY SPACE OF SINGULARITY BY QUANTIUM-ASPIRATING FLUCTUATION. SIMULATION
It is based on an experimental computer simulation of a spatio-temporal singularity, through a quantum fluctuation of the vacuum and the way in which a vortex space is generated, on the Planck scale, in an inflationary way, generating a vortex and a universe. parallel.
In this phase of the simulation, we observe, besides the quantum fluctuation of the vacuum, the formation of the tissue of the temporal space, the fundamental particles of the standard physical model, as well as the appearance of dynamic quantum fields, of the quantum gravity in loop, exotic particles and dark matter, the generation of an inflationary field is also considered, the Higgs field, through said singularity, the gravitational waves caused and a black hole of primordial type.
Another aspect to emphasize in the simulation is the importance of scientific knowledge in terms of unification of relativistic physics with the predicted assumptions in quantum physics, such as the particle wave duality, the wave function, the principle of indeterminacy, superposition Quantum, quantum entanglements, Higgs field, couplings in particle energy levels, quantum gravity and gravitational waves caused by a wormhole or a Rossen-Einstein bridge in Planck rotation, beyond the physical model of standad, with dimensions Extras, exotic particles, dark matter and interactions of ordinary matter with dark matter or dark energy

You can observe the creation of a big bang through a vortex of temporal space resulting in a universe in parallel:
The importance of this scientific development is the discovery of new interactions of fundamental particles with particles that are candidates for dark matter; new exotic or supersymmetric particles, in addition to entering inside a black hole showing the traces of Hawking radiation and unraveling the mysteries of the temporal space tissue; Quantum interleaving of particles or the wave function with the information of the present and future past:

This new singularity would generate an inflationary field, creating new space with dark matter and dark energy, since the fundamental particles can not travel faster than light, this inflationary field would be in charge of weaving and creating new space time, as it expanded , converting the new singularity into temporary space, into a new universe in creation, with the unification of the fundamental forces.

Il est basé sur les observations et les transformations des fonctions d'onde et d'énergie par simulation informatique, détectant et analysant la génération de la gravité quantique en boucle, l'interaction des champs de la dynamique de la gravité quantique, qui font partie de la structure fondamentale du tissu de l'espace temporel:
Les générateurs de fluctuations du vide quantique constituent la structure de base de notre univers à l'échelle de Planck. En plus d’interagir avec la matière noire par le biais de trous noirs de type primaire et d’être à l’origine des états énergétiques de base par fluctuation du vide quantique, de la gravité quantique à l’échelle de Planck, en plus d’interagir avec d’autres champs tels que l'électromagnétique, la force faible, le fort nucléaire ou les ondes gravitationnelles à une échelle relativiste.
L'importance de cette observation est que la gravité de boucle quantique (LQG) est une théorie de la gravité quantique, qui tente de fusionner la mécanique quantique et la relativité générale tout en incorporant des particules modèles standard. L'idée clé de la relativité générale selon laquelle l'espace-temps est une entité dynamique, et non un cadre fixe, est prise au sérieux.
Pour ce faire, dans la théorie LQG, l'espace et le temps sont quantifiés, de manière analogue à la manière dont des quantités telles que l'énergie et la quantité de mouvement sont quantifiées en mécanique quantique. La théorie donne une image physique de l'espace-temps où l'espace et le temps sont granulaires et discrets directement à cause de la quantification ainsi que des photons dans la théorie quantique de l'électromagnétisme et des niveaux d'énergie discrets des atomes. Il y a une distance minimale.
La structure de l'espace préfère un tissu extrêmement fin ou une toile tissée de boucles finies. Ces réseaux de boucle sont appelés réseaux de spin. L'évolution d'un filet à filer, ou mousse à filer, a une échelle de l'ordre de la longueur de Planck, environ 10 à 35 mètres, et il n'y a pas de plus petites échelles. Par conséquent, non seulement la matière, mais l’espace lui-même préfère une structure atomique.
Les vastes domaines de recherche ont été développés dans plusieurs directions impliquant une trentaine de groupes de recherche du monde entier. [1] Tout le monde partage les hypothèses physiques de base et la description mathématique de l'espace quantique. L'enquête suit deux directions: la gravité quantique de la boucle canonique plus traditionnelle et la gravité quantique de la nouvelle boucle covariante, appelée théorie de la mousse de spin.
Les conséquences physiques de la théorie se déroulent dans plusieurs directions. La plus développée est appliquée à la cosmologie, appelée cosmologie de la boucle quantique (LQC), l'étude du premier univers et la physique du Big Bang. Sa plus grande conséquence est que l'évolution de l'univers continue au-delà du Big Bang, appelée Big Bounce.

QUANTIC ENCRYPTION OF INFORMATION BY TRANSFORMATIONS OF WAVES AND ENERGY
Explouniverse Quantum encryption of information.
For a better understanding of the concept of Explouniverso quantum encryption of information, we must take into account other concepts, theories, observation and preditions made previously in quantum physics; The EPR paradox, Quantum interlacing, quantum overlap, Bridges of Rossen Einstein.
The EPR Paradox, formulated by Albert Einstein, Boris Podolsky and Nathan Rosen in 1935. With this mental experiment, quantum mechanics was questioned, trying to solve the problem that arose.
Quantum entanglement
To understand the EPR Paradox, one must first know what quantum entanglement is. This term was coined by Erwin Schrödinger to describe a phenomenon of quantum mechanics, from which its possible application was not known at the beginning. Quantum entanglement says that a set of entangled particles cannot be defined as individual particles with defined states, but only as a system with a single wave function for the entire system.
Interlacing is a quantum phenomenon, without a classical equivalent, in which the quantum states of two or more objects must be described by a single state that involves all objects in the system, even when the objects are spatially separated. This leads to correlations between observable physical properties.
For example, it is possible to prepare two particles in a single quantum state of null spin, so that when it is observed that one turns up, the other will automatically receive a "signal" and will be shown as turning down, despite the impossibility of predict, according to the quantum mechanics postulates, which quantum state will be observed.
These strong correlations make the measurements made on a system appear to be instantly influencing other systems that are linked to it, and suggest that some influence would have to be spreading instantly between the systems, despite the separation between them.

EPR paradox
The EPR Paradox, the Achilles heel of quantum mechanics
Quantum entanglement was raised by Einstein, Podolsky and Rosen as an argument against quantum mechanics. The very idea of quantum entanglement violated the principle of locality, stating that two or more particles could be in different unverifiable states because it is impossible to obtain useful information about particle measurements.
The experiment proposed by EPR consists of two particles that interacted in the past and remain in an intertwined state. Two observers receive each of the particles. If an observer measures the inertia of one of them, he knows what the inertia of the other is. If you measure the position, thanks to quantum entanglement and the uncertainty principle, you can know the position of the other particle instantaneously, which contradicts common sense.
The EPR paradox is in contradiction with the theory of relativity, since information is apparently transmitted instantaneously between the two particles. According to EPR, this theory predicts a phenomenon (that of instant distance action) but does not allow deterministic predictions about it; Therefore, quantum mechanics is an incomplete theory.
The EPR Paradox, the Achilles heel of quantum mechanics
This paradox criticizes two crucial concepts. On the one hand the non-locality of quantum mechanics (that is, the possibility of distance action). On the other, the measurement problem. In classical physics, measuring a system is to reveal properties that were present in it. That is, it is a deterministic operation. In quantum mechanics, it is a mistake to assume the latter. The system will change uncontrollably during the measurement process, and we can only calculate the probabilities of obtaining one result or another.
Bell's theorem
Until 1964, this debate belonged to the domain of the philosophy of science. At that time, John Bell proposed a mathematical way to verify the EPR paradox. Bell managed to deduce some inequalities assuming that the quantum mechanics measurement process obeys deterministic laws. In addition, he assumed the location, that is, taking into account the criticisms of EPR. If Einstein was right, Bell's inequalities are true and quantum theory is incomplete. If the quantum theory is complete, these inequalities will be violated.
From 1976 onwards, numerous experiments have been carried out. All of them have resulted in a violation of Bell's inequalities. A triumph for quantum theory, so far it has demonstrated high precision in the description of the subatomic world. Even in spite of his well-known predictions at odds with common sense and everyday experience.
Bridges of Rossen Einstein.
In physics, a wormhole, also known as the Einstein-Rosen bridge, is a hypothetical topological characteristic of a space-time, described in the equations of general relativity, which essentially consists of a shortcut through space and time . A wormhole has at least two ends connected to a single throat, through which matter could travel. To date, no evidence has been found that known space-time contains structures of this type, so it is currently only a theoretical possibility in science.
Fundamental principle of quantum mechanics
Quantum superposition is a fundamental principle of quantum mechanics that holds that a physical system, such as an electron, exists partly in all its theoretically possible states (or the configuration of its properties) simultaneously, but, when measured, gives a result that corresponds to only one of the possible configurations (as described in the interpretation of quantum mechanics). More specifically, in quantum mechanics, any observable quantity corresponds to an autovector of a hermetic linear operator. The linear combination of two or more autovectors results in the quantum superposition of two or more quantity values. If the quantity is measured, then, the projection postulate establishes that the state collapses randomly on one of the values of the superposition (with a probability proportional to the square of the amplitude of that autovector in the linear combination). Immediately after the measurement, the system status will be the eigenvector corresponding to the measured eigenvalue.
The Planck length is part of the natural unit system, and is calculated from three fundamental constants: the speed of light, the Planck constant and the gravitational constant. It is equivalent to the distance a photon travels, traveling at the speed of light, in Planck's time.
The Planck Length is defined as:
{\ displaystyle \ ell _ {P} = {\ sqrt {\ frac {\ hbar G} {c ^ {3}}}} \ approx 1.616199 (97) \ times 10 ^ {- 35} {\ mbox {meters} }} {\ displaystyle \ ell _ {P} = {\ sqrt {\ frac {\ hbar G} {c ^ {3}}}} \ approx 1.616199 (97) \ times 10 ^ {- 35} {\ mbox { meters}}} 1 2
where c is the speed of light in a vacuum, G is the universal gravitation constant, and {\ displaystyle \ hbar} \ hbar is the Planck Constant reduced.
The two digits in parentheses are the estimated standard error, associated with the reported numerical value.
Planck length and quantum structure of space
Throughout the domain of classical physics ranging from Newtonian mechanics to the theory of general relativity, space is considered to be an infinitely divisible continuum and that seen under the microscope is locally as the Euclidean space.
However, at scales of length as incredibly small as Planck's length, the classical conception of space as a locally Euclidean continuum is expected to be invalid and at those scales the space does in fact have some kind of quantum probabilistic behavior. Another situation in which quantum effects are expected to be important is when Ricci's scalar curvature is of the order of the inverse of the Planck length square:
Being a singularity, in this case caused by a black hole of the primary type, the predictable quantum effects when the curvature is close to that value should be treated by some kind of quantum theory of gravitation. Quantum Gravity Loops. https://youtu.be/a4wRfypGYSU
Primordial black holes;
A primordial black hole is a black hole that was not formed due to the gravitational collapse of a star but to the extreme density of the Universe at the beginning of its expansion. According to the standard model, during the moments that followed the Big Bang the pressure and temperature of the Universe were extremely high. Under these conditions, simple fluctuations in the density of matter could cause regions of space dense enough to generate black holes. Although most of the dense regions would be dispersed by the expansion of the Universe, a primordial black hole would be stable, lasting until today. One of its main characteristics is that they are at the Plancnk scale, and may be the cause of dark matter, these black holes of the primary type being the cause of interactions with dark matter. In addition all the properties conserve a black hole, being able even to form bridges of Rossen Einsteins with exit to another portal, through the Hawkins Radiation.
QUANTIC ENCRYPTION OF INFORMATION FOR WAVE AND ENERGY TRANSFORMATIONS
Explouniverse Quantum encryption of information.
QUANTIC ENCRYPTION OF INFORMATION FOR WAVE AND ENERGY TRANSFORMATIONS
Explouniverse Quantum encryption of information.
New method of encryption of information by means of wave and energy transformations, through wave and energy transformations in the Planck scale, when solving the above, the approximate equivalent value of this unit with respect to the meter will be shown:
{\ displaystyle 1 \ \ ell _ {\ mathrm {P}} \ approx 1.616 \; 229 (38) \ times 10 ^ {- 35} \ \ mathrm {m}} {\ displaystyle 1 \ \ ell _ {\ mathrm {P}} \ approx 1.616 \; 229 (38) \ times 10 ^ - 35} \ \ mathrm {m}}
where {\ displaystyle c} c is the speed of light in a vacuum, G is the gravitational constant and ħ is the Planck constant reduced. The two digits in brackets are the estimated standard error associated with the reported numerical value. [2. 3]
The method consists of transforming PLanck scale information to energy ranges 32 K or 64 k between the energy range that ranges between 32000 and 64000 Gev of energy; being possible for human sight from these ranges of energy.
The information that the quantum state of a photon when intertwined with another photon remains intrinsic between the two intertwined photons, if one of the photons is aspirated by a black hole of primordial type at Planck scale by a quantum vacuum fluctuation, while the another remains outside the event horizon of the black hole; the first photon will contain the information of the quantum state of the second photon that has moved through a bridge of Rossen Einstein in the black hole of the primordial type, at its exit in the second portal, through the Hawking Radiation, in another temporal spatial vector of the universe, or in another multiverse, has generated another quantum fluctuation of emptiness; entwined by a wormhole by Rossen Einstein, through a radiation exit portal by Hawkings Radiation and its information remains intrinsic, therefore information is obtained from wave levels and energies, hitherto undecipherable, just its coding and Decoding is possible through this interlacing of fundamental particles.
While a particle retains its state before the second particle, it retains the information of the first intrinsic particle; By developing the transformations of the Planck scale at a nanometric scale at a metric scale, it generates a visible wave frequency for the human eye.
The Planck (ℓP) or hodon length (term coined in 1926 by Robert Lévi) is the distance or length scale below which the space is expected to cease to have a classical geometry. A predictably lower measure cannot be adequately treated in current physical models due to the occurrence of quantum gravity effects. It would be observable through another method of math that would be Loops Quantum Gravity, dynamic fields of quantum gravity, generators of vacuum fluctuations and therefore of energies in the vacuum of the temporal space structure.

Higgs Inflation, Reheating and Gravitino Production in No-Scale Supersymmetric GUTs
/ Ellis, John (King's Coll. London ; CERN) ; He, Hong-Jian (Tsinghua U., Beijing, CHEP ; Peking U., CHEP) ; Xianyu, Zhong-Zhi (Harvard U., Dept. Math. ; Harvard U., Phys. Dept.)
We extend our previous study of supersymmetric Higgs inflation in the context of no-scale supergravity and grand unification, to include models based on the flipped SU(5) and the Pati-Salam group. Like the previous SU(5) GUT model, these yield a class of inflation models whose inflation predictions interpolate between those of the quadratic chaotic inflation and Starobinsky-like inflation, while also avoiding tension with proton decay limits.

We present a Grand Unified Theory (GUT) that has GUT fields with masses of the order of a TeV, but at the same time preserves (at the one-loop level) the success of gauge-coupling unification of the MSSM and the smallness of proton decay operators. This scenario is based on a five-dimensional theory with the extra dimension compactified as in the Randall-Sundrum model. [...]

The Evolution of Quantum Field Theory, From QED to Grand Unification
/ Hooft, Gerard 't (Utrecht U. ; Utrecht U., Spinoza Inst.)
In the early 1970s, after a slow start, and lots of hurdles, Quantum Field Theory emerged as the superior doctrine for understanding the interactions between relativistic sub-atomic particles. After the conditions for a relativistic field theoretical model to be renormalizable were established, there were two other developments that quickly accelerated acceptance of this approach: first the Brout-Englert-Higgs mechanism, and then asymptotic freedom.

*** Webcast link at the bottom of the Indico page ***
General description of the course
Quantum computing is one the most promising new trends in information processing. In this course, we will introduce from scratch the basic concepts of the quantum circuit model (qubits, gates and measures) and use them to study some of the most important quantum algorithms and protocols, including those that can be implemented with a few qubits (BB84, quantum teleportation, superdense coding...) as well as those that require multi-qubit systems (Deutsch-Jozsa, Grover, Shor..) [...]

W-like measurement of the Z boson mass using dimuon events collected in pp collisions at $\sqrt{s} = 7~\mathrm{TeV}$
/CMS Collaboration
The mass of the Z boson is measured using a sample of $\mathrm{Z}\rightarrow\mu\mu$ events, where one of the two muons is removed from the event to form the $\mathrm{W}^\mathrm{like}$ candidate. This procedure provides a proof of principle and a quantitative validation of analysis techniques developed for a high-precision measurement of the W boson mass in $\mathrm{W}\rightarrow\mu\nu$ events.

Towards the origin?
/ Treille, Daniel (Zurich, ETH)
Traveling backward in time along the timeline of the Universe, we underline what is known experimentally, how sound is our understanding at various moments of its evolution and, towards the origin, at which point hypotheses start to replace certainties..

A View of Flavour Physics in 2021
/ Barbieri, Riccardo (Pisa, Scuola Normale Superiore)
Based on a view of current flavour physics and motivated by the hierarchy problem and by the pattern of quark masses and mixings, I describe a picture of flavour physics that should give rise in a not too distant future to observable deviations from the SM in Higgs compositeness and/or in B-decays with violations of Lepton Flavour Universality, as hinted by current data, or perhaps even in supersymmetry, depending on the specific realisation..

Reconstruction in an imaging calorimeter for HL-LHC
/ Martelli, Arabella (Imperial Coll., London)
/CMS Collaboration
The CMS endcap calorimeter upgrade for the high-luminosity LHC (HL-LHC) uses,
for the most part, silicon sensors to achieve radiation tolerance, with the further benefit of a very high readout granularity.
Developing a reconstruction sequence that fully exploits the granularity,
and other significant features of the detector like precision timing, is a challenging task. [...]
