Long-term aging studies on Resistive Plate Chambers (RPC) of the CMS muon system for HL-LHC / Gelmi, Andrea (INFN, Bari ; Bari U.) /CMS Collaboration
During the phase II of the LHC physics program, called High Luminosity LHC (HL-LHC), the accelerator will increase the instantaneous luminosity up to 5$\times$10$^{34}$cm$^{-2}$s$^{-1}$, providing to experiments an additional integrated luminosity of about 3000 fb$^{-1}$ over 10 years of operation, starting in 2026. The present Compact Muon Solenoid (CMS) Resistive Plate Chambers (RPC) system has been certified for 10 LHC years operation, at maximum background rate of 300 Hz/cm$^{2}$ and 50 mC/cm$^{2}$ as integrated charge.

Geant4 simulation of a Triple-GEM detector exposed to the CHARM field at CERN / Vai, Ilaria (INFN, Pavia ; Pavia U.) /CMS Collaboration
The ME0 station has been proposed for the installation in the CMS muon system in the region $2.03 < \vert \eta \vert < 2.82$, with the aim of increasing the detector acceptance for physics with muons. This region, presently not instrumented, is characterized by a very harsh radiation environment, which can reach rates up to 30 kHz/cm$^2$ and an integrated charge of the order of 200 mC/cm$^2$ over ten years of operation.

Electromagnetism and hidden vector fields in modified gravity theories: spontaneous and induced vectorization / Annulli, Lorenzo (Lisbon U.) ; Cardoso, Vitor (Lisbon U. ; CERN) ; Gualtieri, Leonardo (INFN, Rome)
In General Relativity, Maxwell's equations are embedded in curved spacetime through the minimal prescription, but this could change if strong-gravity modifications are present. [...]

Particle physics applications of the AWAKE acceleration scheme / Caldwell, A. (Munich, Max Planck Inst.) ; Chappell, J. (University Coll. London) ; Crivelli, P. (ETH, Zurich (main)) ; Depero, E. (ETH, Zurich (main)) ; Gall, J. (CERN) ; Gninenko, S. (Moscow, INR) ; Gschwendtner, E. (CERN) ; Hartin, A. (University Coll. London) ; Keeble, F. (University Coll. London) ; Osborne, J. (CERN) et al.
The AWAKE experiment had a very successful Run 1 (2016-8), demonstrating proton-driven plasma wakefield acceleration for the first time, through the observation of the modulation of a long proton bunch into micro-bunches and the acceleration of electrons up to 2 GeV in 10 m of plasma. [...]
