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 the $B^+_c\rightarrow \chi_{c1}(3872)\pi^+$ decay
A search for the decay $B^+_c\rightarrow \chi_{c1}(3872)\pi^+$ is reported using proton-proton collision data collected with the LHCb detector between 2011 and 2018 at centre-of-mass energies of 7, 8, and 13 $TeV$, corresponding to an integrated luminosity of $9fb^{-1}$. [...]

Physics case for low-$\sqrt{s}$ QCD studies at FCC-ee / Verbytskyi, Andrii (Garching, Max Planck Inst.) ; d'Enterria, David (CERN) ; Monni, Pier Francesco (CERN) ; Skands, Peter (Monash U.)
Measurements of hadronic final states in $e^{+}e^{-}$ collisions at centre-of-mass (CM) energies below the Z peak can notably extend the FCC-ee physics reach in terms of precision quantum chromodynamics (QCD) studies. [...]

Long-Baseline Atom Interferometry / TVLBAI Proto Collaboration
Long-baseline atom interferometry is a promising technique for probing various aspects of fundamental physics, astrophysics and cosmology, including searches for ultralight dark matter (ULDM) and for gravitational waves (GWs) in the frequency range around 1~Hz that is not covered by present and planned detectors using laser interferometry.

Precision Tests in $b\to s\ell^+\ell^-$ ($\ell=e,\mu$) at FCC-ee / Bordone, Marzia (Zurich U. ; CERN) ; Cornella, Claudia (CERN) ; Davighi, Joe (CERN)
The rare semi-leptonic decays $B\to K^\ast \ell^+\ell^-$, with $\ell=e, \mu$, are highly sensitive to new physics (NP) due to their suppression in the Standard Model (SM). [...]
