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.

Observation of electroweak production of pairs of Z bosons in proton-proton collisions at 13 TeV
The first evidence of electroweak (EW) production of pairs of Z bosons in association with two jets ($\text{jj}$) in the final state $ \mathrm{Z}\mathrm{Z} \text{jj}\to\ell\ell\nu\nu \text{jj} $, where $ \ell = \mathrm{e}, \mu $, is reported by the CMS experiment. [...]

First Search for Quirks at the LHC with the FASER Experiment / Welch, Eli Marcel (University of California Irvine (US)) ; Jofrehei, Arash (Universite de Geneve (CH)) ; Pizarro Medina, Andrea (Universite de Geneve (CH)) /FASER Collaboration
Quirks are particles that have Standard Model interactions while also interacting through infracolor (IC), a new strong force. In models where the IC confinement scale, $\Lambda$, is much less than the quirk mass, quirk pairs produced at colliders are connected by an IC string force and oscillate around their center of mass with unusual trajectories that escape traditional particle searches.

Data-Driven Dynamic Modeling of a Tendon-Actuated Continuum Robot / Hansen, Harald Minde (CERN) ; Sæbø, Bjørn Kåre (Norwegian U. Sci. Tech.) ; Pettersen, Kristin Y. (Norwegian U. Sci. Tech.) ; Gravdahl, Jan Tommy (Norwegian U. Sci. Tech.) ; Di Castro, Mario (CERN)
Developing dynamic models for tendon-driven continuum robots is challenging due to their nonlinear, high-dimensional, and friction-dominated dynamics. [...]

Mapping jet substructure in heavy-ion collisions with track functions / Barata, João (CERN) ; Go, Yeonju (Brookhaven Natl. Lab.) ; Pablos, Daniel (Oviedo U. ; ICTEA, Oviedo)
We investigate the dynamics of high-energy QCD cascades in heavy-ion collisions, focusing on modifications to jets' substructure induced by the presence of a quark-gluon plasma (QGP). [...]

Angular Analysis of $B \to D^{*}\ell \barν_{\ell}$ from Lattice and Experiment: $|V_{cb}|$ and New Physics Constraints / Bordone, Marzia (U. Mainz, PRISMA) ; Heald, Ollie (Southampton U.) ; Jüttner, Andreas (Southampton U. ; CERN)
We present a combined angular analysis within and beyond the Standard Model (SM) of experimental measurements for the $B \to D^{*}\ell \barν_{\ell}$ angular coefficients provided by the Belle collaboration, together with lattice-calculated hadronic form-factor data from the HPQCD, JLQCD, and FNAL/MILC collaborations.
