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.

Measurement of the W boson decay branching fraction ratio $ \mathcal{B}(\mathrm{ W \to c q })/\mathcal{B}(\mathrm{{W}\to q \bar{q}{}^{'}}) $ in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
The most precise measurement to date of the W boson hadronic decay branching fraction ratio $ R_\mathrm{c}^{\mathrm{W}}=\mathcal{B}(\mathrm{ W \to c q })/\mathcal{B}(\mathrm{{W}\to q \bar{q}{}^{'}}) $ is presented. [...]

Discriminating between Pseudoscalar Higgs and Toponium States at the LHC and Beyond / Djouadi, Abdelhak (Annecy, LAPP ; Granada U., Theor. Phys. Astrophys.) ; Ellis, John (King's Coll. London ; CERN) ; Quevillon, Jeremie (Annecy, LAPP)
We discuss ways to discriminate at hadron colliders between a quasi-bound toponium state and a pseudoscalar Higgs boson A, as predicted in many extensions of the Standard Model. [...]

On Determining $\alpha_s(m_Z)$ from Dijets in $e^+e^-$ Thrust / Benitez, Miguel A. (Salamanca U., IUFFyM) ; Hoang, Andre H. (Vienna U.) ; Mateu, Vicent (Salamanca U., IUFFyM) ; Stewart, Iain W. (Vienna U. ; MIT) ; Vita, Gherardo (CERN)
We update a previous N$^3$LL$^\prime$+${\cal O}(\alpha_s^3)$ determination of the strong coupling from a global fit to thrust data by including newly available perturbative ingredients, upgrading the renormalization scales to include a fully canonical scaling region, and implementing the log resummation in a way which ensures the integrated cross section is unaffected by the the leading $1/Q$ hadronization power corrections.

On the Interplay of Constraints from $B_s$, $D$, and $K$ Meson Mixing in $Z^\prime$ Models with Implications for $b\to s \nu\bar\nu$ Transitions / Buras, Andrzej J. (TUM-IAS, Munich) ; Stangl, Peter (CERN)
Within $Z^\prime$ models, neutral meson mixing severely constrains beyond the Standard Model (SM) effects in flavour changing neutral current (FCNC) processes. [...]

Towards a differential $\mathrm{t\bar{t}W}$ cross section measurement at CMS / Marckx, David (Gent U. ; Rochester U.)
Top quark pair production in association with a W boson is a rare standard model process that has proven to be an intriguing puzzle for theorists and experimentalists alike. [...]

NNLO fits of top-quark mass using total, single-differential and double-differential $t\bar{t}+X$ cross-section data / Alekhin, S. ; Garzelli, M.V. ; Mazzitelli, J. ; Moch, S.-O. ; Zenaiev, O.
We describe the fits of the top-quark mass value at NNLO using as input the double-differential distributions in rapidity and invariant mass of $t\bar{t}$ pairs obtained by the ATLAS and CMS collaborations from unfolding of their experimental data to the parton level, compared to NNLO theory predictions.

Measurement of light-by-light scattering and the Breit-Wheeler process, and search for axion-like particles in ultraperipheral PbPb collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 5.02 TeV
Measurements of light-by-light scattering (LbL, $ \gamma\gamma\to\gamma\gamma $) and the Breit-Wheeler process (BW, $ \gamma\gamma\to\mathrm{e}^+\mathrm{e}^- $) are reported in ultraperipheral PbPb collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV. [...]

CMS RPC performance and operation in LHC Run 3 / CMS Collaboration
The CMS experiment has collected more than 180 fb$^{-1}$ of proton-proton collision data at a 13.6 TeV center-of-mass energy in Run 3 data taking (2022, 2023 and 2024). The CMS RPC system faces the challenge of the LHC delivered instantaneous luminosity of up to 2 x 10$^{34}$ cm$^{-2}$s$^{-1}$, providing redundant information for robust muon triggering, reconstruction and identification.
