Mounting Evidence for the Violation of Lepton Flavor Universality / Crivellin, Andreas (Zurich U. ; PSI, Villigen ; CERN) ; Hoferichter, Martin (Bern U.)
The Standard Model (SM) of particle physics was finalized in its current form in the mid-1970s, and has been extensively tested and confirmed ever since, with the discovery of the Higgs boson in 2012 being the last missing piece. While no new particles have been directly discovered at the Large Hadron Collider (LHC) at CERN so far, precision observables sensitive to quantum effects of new particles have accumulated intriguing hints for physics beyond the SM.

Impact of new operational dosimetric quantities on individual monitoring services / Caresana, M (Milan, Polytech.) ; Garlati, L (Milan, Polytech.) ; Zorloni, G (Milan, Polytech.) ; Behrens, R (Braunschweig, Phys. Tech. Bund.) ; Otto, T (CERN) ; Minchillo, G (Euratom, Ispra) ; Rossi, F (Unlisted, IT)
The new operational dosimetric quantities framework, proposed in the ICRU95 report, has stimulated the scientific community to start investigations that aim to assess its impact on radiation protection practices. As part of this effort, the present study describes an inter-comparison exercise among individual monitoring services (IMSs) on passive whole-body dosimetry [...]

Heavy-ion induced single event effects and latent damages in SiC power MOSFETs / Martinella, C (Jyvaskyla U. ; CERN ; ETH, Zurich (main)) ; Natzke, P (ETH, Zurich (main)) ; Alia, R G (CERN) ; Kadi, Y (CERN) ; Niskanen, K (Jyvaskyla U.) ; Rossi, M (Jyvaskyla U.) ; Jaatinen, J (Jyvaskyla U.) ; Kettunen, H (Jyvaskyla U.) ; Tsibizov, A (ETH, Zurich (main)) ; Grossner, U (ETH, Zurich (main)) et al.
The advantages of silicon carbide (SiC) power MOSFETs make this technology attractive for space, avionics and high-energy accelerator applications. However, the current commercial technologies are still susceptible to Single Event Effects (SEEs) and latent damages induced by the radiation environment. [...]

Precision luminosity measurement with the CMS detector at HL-LHC / Pásztor, Gabriella (Eotvos U., Dept. Atomic Phys.) /CMS Collaboration
The high-luminosity upgrade of the LHC (HL-LHC) is foreseen to reach an instantaneous luminosity a factor of five to seven times the nominal LHC design value. The resulting, unprecedented requirements for background monitoring and luminosity measurement create the need for new high-precision instrumentation at CMS, using radiation-hard detector technologies.

Quarkonium polarization in Pb-Pb collisions at the LHC with ALICE / Michelettion, Luca (INFN, Turin) /ALICE Collaboration
Polarization measurements represent an important tool to investigate the production mechanisms of quarkonia, bound states of two heavy quarks (charm or bottom), in proton-proton collisions. Nevertheless, the very small polarization measured at the LHC represents a long-lasting challenge for theoretical models. [...]

Search for pair production of top squarks and for dark matter in final states with two leptons using data collected by the ATLAS experiment during the LHC Run 2 / Gravili, F G (Salento U. ; INFN, Lecce) /ATLAS Collaboration
A search for the direct pair production of top squarks $(\tilde{t})$ and for dark matter in events with two opposite-charge leptons, jets and missing transverse momentum is presented. The analysis is based on 139 fb$^{-1}$ of proton-proton collision data recorded by the ATLAS experiment at the Large Hadron Collider (LHC) at $\sqrt{s} = 13$TeV. [...]

Azimuthal asymmetries in unpolarized semi-inclusive deep inelastic scattering at COMPASS / Moretti, Andrea (Trieste U. ; INFN, Trieste) /COMPASS Collaboration
The amplitude of the modulations in the azimuthal angle distribution (azimuthal asymmetries) of hadrons produced in the semi-inclusive deep inelastic scattering on an unpolarized nucleon carries information on the intrinsic transverse momentum of the quark and on the Boer-Mulders parton distribution function. Using the data collected with a 160 GeV muon beam scattering off a liquid-hydrogen target, the COMPASS Collaboration has recently measured the azimuthal asymmetries $A^{\mathrm{cos} φ_h}_{UU}, A^{\mathrm{cos}2φ_h}_{UU}$ and $A^{\mathrm{cos}φ_h}_{LU}$ of charged hadrons.

ME0 project for the Triple-GEM upgrade of the CMS muon spectrometer: Design, preliminary performance and R&D; perspective / Fiorina, D (INFN, Pavia ; Pavia U.) /CMS Collaboration
In the framework of the HL-LHC project, the upgrade of the CMS Muon System envisages the installation of three new muon stations based on the GEM technology, named as GE1/1, GE2/1 and ME0. The CMS GEM Group has developed a novel construction design of GE1/1 triple-GEM detectors; in particular, a new self-stretching technique has been introduced to mechanically stretch the GEM foils without using spacer grids or glue inside the gas volume.

Measurement of the track impact parameters resolution with the ATLAS experiment at LHC using 2016-2018 data / Magliocca, C (U. Geneva (main)) /ATLAS Collaboration
This study presents the measurement of the impact parameter distributions to test the resolution of the tracks reconstructed with the ATLAS inner detector at the LHC. It has been performed using proton-proton collision data collected at $\sqrt{s} = 13$TeV between 2016 and 2018. [...]
