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.

Threshold resummation for the production of four top quarks at the LHC / van Beekveld, Melissa (Oxford U., Theor. Phys.) ; Kulesza, Anna (Munster U., ITP ; CERN) ; Valero, Laura Moreno (Munster U., ITP)
We compute the total cross section for $t\bar{t}t\bar{t}$ production at next-to-leading logarithmic (NLL$^{\prime}$) accuracy. [...]

Measurement of the cross section of top quark-antiquark pair production in association with a W boson in proton-proton collisions at $\sqrt{s} = 13$ TeV / Tran, Tu Thong
The production of a top quark-antiquark pair in association with a W boson is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV. [...]

Search for exotic long-lived particles at CLIC / Kucharczyk, Marcin (Polish Academy of Sciences (PL)) ; Goncerz, Mateusz Jacek (Polish Academy of Sciences (PL))
A study of the sensitivity of the CLIC_ILD detector model for massive long-lived particles produced in the decay of the Higgs boson is presented, using a data sample of e+e− collisions at $\sqrt{s}$ = 350 GeV and $\sqrt{s}$ = 3 TeV, corresponding to an integrated luminosity of 1 ab$^{−1}$ and 3 ab$^{−1}$, respectively. The sensitivity range covers long-lived particle lifetimes from 1 to 300 ps, masses between 25 and 50 GeV, and a parent Higgs mass of 126 GeV. [...]

Cornering Large-$N_c$ QCD with Positivity Bounds / Fernandez, Clara (Barcelona, IFAE ; BIST, Barcelona) ; Pomarol, Alex (Barcelona, IFAE ; BIST, Barcelona ; Barcelona, Autonoma U. ; CERN) ; Riva, Francesco (Geneva U., Dept. Theor. Phys.) ; Sciotti, Francesco (Barcelona, IFAE ; BIST, Barcelona)
The simple analytic structure of meson scattering amplitudes in the large-$N_c$ limit, combined with positivity of the spectral density, provides precise predictions on low-energy observables. [...]

Dead-cone searches in heavy-ion collisions using the jet tree / Cunqueiro, Leticia (Rome U.) ; Napoletano, Davide (Milan Bicocca U. ; INFN, Milan) ; Soto-Ontoso, Alba (CERN)
We explore the possibility of using the dead cone of heavy quarks as a region of the Lund plane where medium-induced gluon radiation can be isolated and characterised. [...]

Amplitude analysis of $B^0 \rightarrow \overline{D}^0 D_s^+ \pi^-$ and $B^+ \rightarrow D^- D_s^+ \pi^+$ decays
Resonant contributions in $B^0 \rightarrow \overline{D}{}^0 D^+_s\pi^-$ and $B^+\rightarrow D^- D^+_s\pi^+$ decays are determined with an amplitude analysis, which is performed both separately and simultaneously, where in the latter case isospin symmetry between the decays is assumed [...]

First observation of a doubly charged tetraquark and its neutral partner
A combined amplitude analysis is performed for the decays $B^0 \rightarrow \overline{D}{}^0 D^+_s\pi^-$ and $B^+\rightarrow D^- D^+_s\pi^+$, which are related by isospin symmetry. [...]

A truly cylindrical inner tracker for ALICE / Yüncü, Alperen
After the successful installation and first operation of the upgraded Inner Tracking System (ITS2), which consists of about $10\,$m$^2$ of monolithic silicon pixel sensors, ALICE is pioneering the usage of bent, wafer-scale pixel sensors for the ITS3 for LHC Run 4. [...]
