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.

Study of nuclear effects in charm production in light-ion collisions
The onset of nuclear effects in light-ion collisions is studied by measuring the ratio of $D^0$ meson production between NeNe and OO collisions at a center-of-mass energy per nucleon pair of $5.36\,{\rm TeV}$ recorded by the LHCb detector. [...]

Upgrade of the CMS Muon System with GEM Detectors / Thakur, Shalini (Tarapaca U.) /CMS Collaboration
The CMS detector is being upgraded for the High-Luminosity LHC (HL-LHC) run to begin in 2030. As part of the upgrade, the forward muon system is being strengthened with Gas Electron Multiplier (GEM) detectors to ensure robust performance in high-luminosity and high-background conditions in the forward region of the CMS detector.
