Status of searches in the long-lived particle and dark sectors, including full run-2 and HL-LHC prospects / Alimena, Juliette (Ohio State U.) /ATLAS, CMS and LHCB Collaborations
Particles beyond the standard model can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at the LHC at CERN, these long-lived particles (LLPs) can decay far from the primary proton-proton interaction, or even completely pass through the detector before decaying. [...]

Study of the effects of radiation on the CMS Drift Tubes Muon Detector for the HL-LHC / Gonzalez Caballero, Isidro (Oviedo U.)
The CMS drift tubes (DT) muon detector, built for standing up the LHC expected integrated and instantaneous luminosities, will be used also in the High Luminosity LHC (HL-LHC) at a 5 times larger instantaneous luminosity and, consequently, much higher levels of radiation, reaching about 10 times the LHC integrated luminosity. Initial irradiation tests of a spare DT chamber at the CERN gamma irradiation facility (GIF++), at large (~O(100)) acceleration factor, showed ageing effects resulting in a degradation of the DT cell performance.

Towards a metamaterial approach for fast timing in PET: experimental proof-of-concept / Turtos, R M (CERN ; Milan Bicocca U.) ; Gundacker, S (CERN ; Milan Bicocca U.) ; Auffray, E (CERN ; Milan Bicocca U.) ; Lecoq, P (CERN ; Milan Bicocca U.)
Achieving fast timing in positron emission tomography (PET) at the level of few tens of picoseconds of picoseconds is limited by the photon emission rate of existent materials with standard scintillation mechanisms. [...]

The EFT and FCNC interpretations in the processes with top quarks at CMS / Skovpen, Kirill
In absence of any distinct evidence of new physics phenomena at the LHC, an increasing number of experimental studies aim at probing anomalous effects with an effective field theory (EFT) that represents a comprehensive approach for interpretation of various experimental results. [...]
