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.

Search for Higgs boson exotic decays into Lorentz-boosted light bosons in the four-$\tau$ final state at $\sqrt{s}=13$ TeV with the ATLAS detector
A search for exotic decays of the Higgs boson into a pair of low-mass scalars that subsequently decay into $\tau$-leptons, $H\rightarrow aa\rightarrow \tau^+\tau^-\tau^+\tau^-$, is presented. [...]

Search for new physics in jet scaling patterns of multilepton events at $ \sqrt{s} = $ 13 TeV
A first search for beyond the standard model physics in jet scaling patterns of multilepton events is presented, using a data sample corresponding to an integrated luminosity of 138 fb$ ^{-1} $ of 13 TeV proton-proton collisions recorded by the CMS detector at the LHC. [...]

Large charge meets semiclassics in $\mathcal{N}=4$ super Yang-Mills / Brown, Augustus (Queen Mary, U. of London) ; Galvagno, Francesco (Queen Mary, U. of London) ; Grassi, Alba (U. Geneva (main)) ; Iossa, Cristoforo (U. Geneva (main)) ; Wen, Congkao (Queen Mary, U. of London)
We study the large-charge sector of $\mathcal{N}=4$ super Yang-Mills theory (SYM) with $SU(N)$ gauge group by constructing a special class of half-BPS heavy operators, termed "canonical operators". [...]

Branching fraction measurement of the decay $B^+ \to \psi(2S) \phi(1020) K^+$ / LHCb Collaboration
The branching fraction of the decay $B^+\to \psi(2S)\phi(1020)K^+$, relative to the topologically similar decay $B^+\to J/\psi \phi(1020) K^+$, is measured using proton-proton collision data collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of $9\,\mathrm{fb}^{-1}$.

We employ a covariant formalism to study the evolution of cosmological perturbations during a first-order phase transition, addressing in particular their gauge dependence that have been overlooked so far. [...]

Di-decay signature of new physics particles at intensity frontier experiments / Dalla Valle Garcia, Giovani (KIT, Karlsruhe, IAP) ; Ovchynnikov, Maksym (CERN)
We explore the potential of intensity frontier experiments to search for unstable feebly interacting particles (FIPs) via signatures that offer deeper insights than the standard signature of a single FIP decay. [...]
