A search for lepton-flavour violating $\tau \to 3\mu$ decays with the ATLAS detector
A search for charged lepton flavour violation in $\tau \to 3\mu$ decays is performed in $pp$ collisions at a centre-of-mass energy of 13 TeV using ATLAS data collected between 2016 and 2018, corresponding to an integrated luminosity of 137 $\text{fb}^{-1}$ [...]

Why (and How) LGADs Work: Ionization, Space Charge, and Gain Saturation / Cartiglia, N (INFN, Turin) ; Altamura, A R (INFN, Turin ; Turin U.) ; Arcidiacono, R (INFN, Turin ; Piemonte Orientale U., Alessandria) ; Durando, M (Turin U.) ; Galletto, S (Turin U.) ; Ferrero, M (INFN, Turin) ; Lanteri, L (INFN, Turin ; Turin U.) ; Losana, A (INFN, Turin ; Turin U.) ; Massaccesi, L (INFN, Turin ; Turin U.) ; Menzio, L (CERN) et al.
The temporal resolution of Low-Gain Avalanche Detectors (LGADs), also known as Ultra-Fast Silicon Detectors (UFSDs), is governed by two contributions: jitter, arising from electronic noise and signal slew rate, and the Landau noise term, arising from the non-uniform energy deposition of minimum ionizing particles (MIPs).

Measurement of the $t$-channel single top quark cross section in proton-proton collisions at $\sqrt{s}$ = 5.02 TeV / CMS Collaboration
The single top quark $t$-channel production cross section is measured in proton-proton collisions at the CERN LHC at $\sqrt{s}$ = 5.02 TeV, using data recorded with the CMS detector in 2017, corresponding to an integrated luminosity of 302 pb$^{-1}$, and resulting in the first CMS measurement of the process at that energy.
