ABOUT PREPRINTS
The Preprints collection aims to cover as far as possible all the grey literature in particle physics and its related technologies. The collection contains something like 400,000 documents, out of which about 50% can be accessed electronically. The documents originate from a variety of institutes all over the world. The collection, currently available, starts in 1979 and it has a full coverage of the arXiv.org e-Print archive since its beginning in 1991.

Combined effective field theory interpretation of measurements sensitive to quartic gauge boson couplings in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
A combination of measurements sensitive to anomalous quartic electroweak gauge boson couplings is presented using proton-proton collision data collected by the ATLAS detector at $\sqrt{s} = 13$ TeV at the LHC. [...]

Measurement of hadronic form-factor parameters with an angular analysis of $B^0 \rightarrow D^{*-} \mu^{+} \nu_{\mu}$ decays /LHCb Collaboration
The hadronic form-factor parameters of the $B^{0}\to D^{\ast-} \mu^{+} \nu_\mu$ decay are determined from a differential analysis of the decay rate in dilepton momentum squared, $q^2$, the three helicity angles and the squared invariant mass of the visible system, $m^2_{miss}$. The data sample used corresponds to an integrated luminosity of 3.0 fb$^{-1}$ collected by the LHCb experiment in proton-proton collisions at centre-of-mass energies 7 TeV and 8 TeV [...]

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.

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).
