FLAG Review 2021
/ Flavour Lattice Averaging Group (FLAG) Collaboration
We review lattice results related to pion, kaon, $D$-meson, $B$-meson, and nucleon physics with the aim of making them easily accessible to the nuclear and particle physics communities. More specifically, we report on the determination of the light-quark masses, the form factor $f_+(0)$ arising in the semileptonic $K \to \pi$ transition at zero momentum transfer, as well as the decay constant ratio $f_K/f_\pi$ and its consequences for the CKM matrix elements $V_{us}$ and $V_{ud}$.

QCD thermalization: Ab initio approaches and interdisciplinary connections
/ Berges, Jürgen (U. Heidelberg, ITP) ; Heller, Michal P. (Potsdam, Max Planck Inst.) ; Mazeliauskas, Aleksas (CERN) ; Venugopalan, Raju (Brookhaven)
Heavy-ion collisions at BNL's Relativistic Heavy Ion Collider and CERN's Large Hadron Collider provide strong evidence for the formation of a quark-gluon plasma, with temperatures extracted from relativistic viscous hydrodynamic simulations shown to be well above the transition temperature from hadron matter. How the strongly correlated quark-gluon matter forms in a heavy-ion collision, its properties off-equilibrium, and the thermalization process in the plasma, are outstanding problems in QCD. [...]

Characterisation of a large area silicon photomultiplier
/ Nagai, A. (Geneva U.) ; Alispach, C. (Geneva U.) ; Barbano, A. (Geneva U.) ; Coco, V. (CERN) ; della Volpe, D. (Geneva U.) ; Heller, M. (Geneva U.) ; Montaruli, T. (Geneva U.) ; Njoh, S. (Geneva U.) ; Renier, Y. (Geneva U.) ; Troyano-Pujadas, I. (Geneva U.)
This work illustrates and compares some methods to measure the most relevant parameters of silicon photo-multipliers (\sipm{}s), such as photon detection efficiency as a function of over-voltage and wavelength, dark count rate, optical cross-talk, afterpulse probability. For the measurement of the breakdown voltage, $V_{BD}$, several methods using the current-voltage $IV$ curve are compared, such as the "IV Model", the "relative logarithmic derivative", the "inverse logarithmic derivative", the "second logarithmic derivative", and the "third derivative" models [...]

Hydrodynamic series and hydrodynamization of expanding plasma in kinetic theory
/ Heller, Michal P. (Potsdam, Max Planck Inst. ; Perimeter Inst. Theor. Phys. ; Warsaw, Inst. Nucl. Studies) ; Kurkela, Aleksi (CERN ; Stavanger U.) ; Spaliński, Michal (Warsaw, Inst. Nucl. Studies ; Bialystok U.) ; Svensson, Viktor (Warsaw, Inst. Nucl. Studies ; Potsdam, Max Planck Inst.)
We explore the transition to hydrodynamics in a weakly-coupled model of quark-gluon plasma given by kinetic theory in the relaxation time approximation with conformal symmetry. We demonstrate that the gradient expansion in this model has a vanishing radius of convergence due to the presence of a transient (nonhydrodynamic) mode, in a way similar to results obtained earlier in strongly-coupled gauge theories.

The ALFA Roman Pot Detectors of ATLAS

The ATLAS Roman Pot system is designed to determine the total proton-proton cross-section as well as the luminosity at the Large Hadron Collider (LHC) by measuring elastic proton scattering at very small angles. The system is made of four Roman Pot stations, located in the LHC tunnel in a distance of about 240~m at both sides of the ATLAS interaction point. [...]

Sensitivity recovery for the AX-PET prototype using inter-crystal scattering events

The development of novel detection devices and systems such as the AX-positron emission tomography (PET) demonstrator often introduce or increase the measurement of atypical coincidence events such as inter-crystal scattering (ICS). In more standard systems, ICS events often go undetected and the small measured fraction may be ignored. [...]

/for the CTA Consortium
The prototype of a Davies-Cotton small size telescope (SST-1M) has been designed and developed by a consortium of Polish and Swiss institutions and proposed for the Cherenkov Telescope Array (CTA) observatory. The main purpose of the optical system is to focus the Cherenkov light emitted by extensive air showers in the atmosphere onto the focal plane detectors. [...]
