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.

Fluid perturbations from expanding bubbles in first-order phase transitions / Caprini, Chiara (Geneva U., Dept. Theor. Phys. ; CERN) ; Midiri, Antonino S. (Geneva U., Dept. Theor. Phys.) ; Procacci, Simona (Geneva U., Dept. Theor. Phys.) ; Roper Pol, Alberto (Geneva U., Dept. Theor. Phys.)
We study the power spectrum of the velocity field induced during a first-order phase transition occurring in the radiation-dominated era. [...]

Search for Higgs boson pair production in the $\mathrm{b\bar{b}WW}$ decay channel with two leptons in the final state using proton-proton collision data at $\sqrt{s}$ = 13.6 TeV / CMS Collaboration
A search for Higgs boson pair production is presented, targeting final states where one Higgs boson decays to a pair of bottom quarks and the other Higgs boson decays to two W bosons, both of which decay leptonically, to an electron or a muon, and a neutrino. [...]

Measurement of di-muons from 400 GeV/c protons interacting in a thick molybdenum/tungsten target / Ruf, Thomas /SHiP
Di-muon events emanating from a replica of the SHiP target at the CERN SPS contain a clear signal of \jpsi~production. The production rate is in reasonable agreement with \MCs based on Pythia v8. [...]

Baryogenesis from Exploding Primordial Black Holes / Klipfel, Alexandra P. (MIT) ; Vanvlasselaer, Miguel (Brussels U., IIHE ; U. Barcelona (main)) ; Trifinopoulos, Sokratis (MIT ; CERN ; Zurich U.) ; Kaiser, David I. (MIT)
Exploding primordial black holes can source baryon asymmetry soon after the electroweak phase transition, as high-energy Hawking radiation drives ultrarelativistic shocks in the surrounding plasma. [...]
