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.

The QCD energy-momentum tensor on the lattice: non-perturbative renormalization with $N_f=3$ / Bresciani, Matteo (Trinity Coll., Dublin) ; Brida, Mattia Dalla (Milan Bicocca U. ; INFN, Milan Bicocca) ; Giusti, Leonardo (Milan Bicocca U. ; INFN, Milan Bicocca ; CERN) ; Hirasawa, Mitsuaki (Milan Bicocca U. ; INFN, Milan Bicocca) ; Pepe, Michele (INFN, Milan Bicocca) ; Virzì, Luca (Milan Bicocca U. ; INFN, Milan Bicocca)
We construct the traceless components of the energy-momentum tensor on the lattice for QCD with $N_f=3$ flavours, such that their correlation functions satisfy the appropriate Ward identities in the continuum limit. [...]

Spectral densities from Euclidean correlators via integral transforms: theoretical framework / Giusti, Leonardo (INFN, Milan Bicocca ; Milan Bicocca U. ; CERN) ; Saccardi, Matteo (INFN, Milan Bicocca ; Colorado State U.) ; Toniolo, Diego (INFN, Milan Bicocca ; Milan Bicocca U.)
Spectral densities link experimental measurements to dynamical properties of a quantum field theory which, in turn, can be resolved non-perturbatively from the Euclidean time-dependence of correlation functions. [...]

Transverse Emittance and Emittance Measurements / Kube, Gero (DESY)
Transverse emittance is one of the central figures of merit for charged-particle beams because it connects the microscopic phase-space distribution to macroscopic accelerator performance. [...]

Search for long-lived particles decaying into muons in proton-proton collisions at $\sqrt{s}$ = 13.6 TeV using data scouting / CMS Collaboration
A search for long-lived particles decaying into muons is performed using proton-proton collisions at $\sqrt{s}$ = 13.6 TeV, collected by the CMS experiment at the LHC in 2022 and 2023, corresponding to an integrated luminosity of 62.4 fb$^{-1}$. [...]

Sensor Quality Control and Annealing Studies of HGCAL Silicon Sensors / Gul Dincer, Gizem (Institut für Experimentelle Teilchenphysik, Karlsruhe, Germany) /CMS Collaboration
The CMS detector at the CERN Large Hadron Collider is undergoing major upgrades for the High-Luminosity LHC (HL-LHC), including the replacement of its endcap calorimeters with the High Granularity Calorimeter (HGCAL). The electromagnetic section (CE-E) and the high-radiation regions of the hadronic section (CE-H) will employ radiation-tolerant, fast-response silicon pad sensors, collectively covering a surface area of approximately 620 m².

CMS Phase 2 Outer Tracker 2S Module Assembly / Kumar Pal, Kuldeep (National Institute of Science Education and Research, Jatni, Khorda, Odisha 752050, India Homi Bhabha National Institute, Training School Complex, Anushakti Nagar, Mumbai 400094, India, Odisha, India) /CMS Collaboration
To cope up with enhanced interaction rates during the High Luminosity operation of the LHC (HL-LHC), the CMS Outer Tracker (OT) is being upgraded with specialized strip-strip (2S) modules with capability of track selection at the hardware level. The assembly of such silicon strip tracker modules consist a multi-step procedure with the usage of several machineries and precision fixtures. [...]

The 3D pixel tracker of the CMS Precision Proton Spectrometer in Run 3 / Gianatti, Anna (INFN Sezione di Genova (a); Università di Genova (b), Genova, Italy) /CMS Collaboration
The CMS Precision Proton Spectrometer (PPS) was designed for measuring protons that escape along the LHC beam line after the interaction in CMS. It successfully took data during the LHC Run 2, collecting more than 110 fb-1 of integrated luminosity, and since 2022 is taking data in Run 3, having already collected more than 230 fb-1. [...]
