 Space application: The AMS RICH / Giovacchini, F (Madrid, CIEMAT) /AMS RICH Collaboration A Ring Imaging Cherenkov detector is on board the Alpha Magnetic Spectrometer, for mass and charge identification of charged cosmic rays. AMS is a high-energy particle physics magnetic spectrometer in space, which was successfully installed at the International Space Station on May 2011 to perform accurate measurements of Galactic Cosmic Rays fluxes in the rigidity range from 1 GV to a few TV.

 Development of a FELIX based readout system for ITk strip hybrid module demonstrator for ATLAS Phase-II Upgrade / Wu, W (SKLPPC, Shanghai ; Brookhaven ; Shanghai Jiaotong U.) ; Chen, H (Brookhaven) ; Chen, K (Brookhaven) ; Lanni, F (Brookhaven) ; Stucci, S (Brookhaven) ; Tang, S (Brookhaven) ; Zhivun, E (Brookhaven) The Large Hadron Collider (LHC) will undergo a major upgrade around 2024 with a roughly tenfold increase in luminosity. It results in corresponding increases in particle rates and radiation doses that the current ATLAS Inner Tracking Detector cannot cope with. [...] 2020 - 8 p. - Published in : JINST 15 (2020) P03013

 Tin resonance-ionization schemes for atomic- and nuclear-structure studies / Gustafsson, F P (Leuven U.) ; Ricketts, C M (Manchester U.) ; Reitsma, M L (U. Groningen, VSI) ; Garcia Ruiz, R F (CERN ; MIT) ; Bai, S W (Peking U., SKLNPT) ; Berengut, J C (Heidelberg, Max Planck Inst. ; New South Wales U.) ; Billowes, J (Manchester U.) ; Binnersley, C L (Manchester U.) ; Borschevsky, A (U. Groningen, VSI) ; Cocolios, T E (Leuven U.) et al. This paper presents high-precision spectroscopic measurements of atomic tin using five different resonanceionization schemes performed with the collinear resonance-ionization spectroscopy technique. Isotope shifts were measured for the stable tin isotopes from the $5 s^2 5p^2 ^3P_{0,1,2}$ and $^1S_0$ to the $5s^2 5p6s ^1P_1, ^3P_{1,2}$ and $5s^2 5p7s^1 P_1$ atomic levels.

 Lepton and Photon reconstruction and identification performance in ATLAS and CMS in Run II / Jain, Shilpi (U. Minnesota, Minneapolis (main)) /ATLAS Collaboration ; CMS Collaboration Leptons and photons are not only important for precision physics analyses (e.g. $H\rightarrow\gamma\gamma$), but also are very important handles for a vast number of beyond the Standard Model (BSM) searches.It is important to have a good understanding about their reconstruction, identification and energy scale and resolution.This proceeding summarises the lepton and photon performance results from the two multi-purpose experiments at the Large Hadron Collider (LHC), $viz.$, ATLAS and CMS, using the full Run 2 dataset.In addition, CMS has recently performed the re-calibration of the full Run 2 dataset (referred to as the "Legacy ReReco") with improved detector description in the simulationand updated calibration, alignment etc., in data.

 Looking forward to test the KOTO anomaly with FASER / Kling, Felix (SLAC) ; Trojanowski, Sebastian (Sheffield U. ; NCBJ, Warsaw) The search for light and long-lived particles at the LHC will be intensified in the upcoming years with a prominent role of the new FASER experiment. In this study, we discuss how FASER could independently probe such scenarios relevant for new physics searches at kaon factories. [...] arXiv:2006.10630.- 2020 - 12 p. - Published in : Phys. Rev.

 Dual beam delivery system serving two interaction regions for the Compact Linear Collider / Cilento, Vera (CERN) ; Tomás, Rogelio (CERN) ; Cure, Benoit (CERN) ; Faus-Golfe, Angeles (IJCLab, Orsay) ; Dalena, Barbara (IRFU, Saclay, DACM) ; Levinsen, Yngve (ESS, Lund) The Compact Linear Collider (CLIC) could provide $e^+e^−$ collisions in two detectors simultaneously possibly at a bunch train frequency in the linac twice the baseline design value. In this paper, a novel dual beam delivery system (BDS) design is presented in order to serve two interaction regions (IR1 and IR2) including optics designs and the evaluation of luminosity performance with synchrotron radiation (SR) and solenoid effects for both energy stages of CLIC, 380 GeV and 3 TeV.

The New Small Wheel (NSW), a completely new detector system to be built, is composed of two novel gaseous detectors: Micro-mesh Gaseous Structure (Micromegas) and the small-strip Thin Gap Chamber (sTGC).

 A search for axion-like particles in light-by-light scattering at the CLIC / İnan, S C (Cumhuriyet U.) ; Kisselev, A V (Kurchatov Inst., Moscow) The virtual production of axion-like particles (ALPs) in the light-by-light scattering at the CLIC collider is studied. Both differential and total cross sections are calculated, assuming interaction of the ALP with photons via CP-odd term in the Lagrangian.
