Shocks from Exploding Primordial Black Holes in the Early Universe / Vanvlasselaer, Miguel (Brussels U., IIHE ; U. Barcelona (main)) ; Trifinopoulos, Sokratis (MIT ; CERN ; Zurich U.) ; Klipfel, Alexandra P. (MIT) ; Kaiser, David I. (MIT)
We investigate how Hawking radiation from low-mass primordial black holes deposits energy into the early-universe plasma and show that the resulting phenomena are hydrodynamic rather than purely diffusive. [...]

The photon-energy spectrum in $B\to X_sγ$ to N$^3$LO: light-fermion and large-$N_{\rm c}$ corrections / Fael, Matteo (U. Padua, Dept. Phys. Astron. ; INFN, Padua) ; Lange, Fabian (Zurich U. ; PSI, Villigen) ; Schönwald, Kay (CERN) ; Steinhauser, Matthias (KIT, Karlsruhe, TTP)
We calculate the photon-energy spectrum of the inclusive radiative decay $B\to X_sγ$, induced by the electromagnetic dipole operator $O_7$, to next-to-next-to-next-to-leading order and consider the complete corrections for light fermions, for the contributions with two closed massive fermion loops, and for the limit of large QCD colour factors $N_{\rm c}$ in the remaining part.

$gg \to ZH$ at NLO matched to parton showers with ggxy and POWHEG / Davies, Joshua (Liverpool U., Dept. Math.) ; Schönwald, Kay (CERN) ; Steinhauser, Matthias (KIT, Karlsruhe, TTP) ; Stremmer, Daniel (KIT, Karlsruhe, TTP)
We implement the recently-calculated analytic expressions for the next-to-leading order QCD corrections to $gg\to ZH$ in ggxy. [...]

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).
