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 CMS Barrel Calorimeter Processor near production (BCP V2) board evaluation / Goadhouse, Stephen David (Virginia U.) ; Nikitas Loukass
The Barrel Calorimeter Processor (BCP), based on ATCA blade architecture, has been developed for the readout of the electromagnetic calorimeter (ECAL) and hadron calorimeter (HCAL) subdetectors of the CMS experiment. The BCP supports 120 optical receive channels of up to 25 Gbps, 72 optical transmit channels of up to 25 Gbps, an AMD XCVU13P UltraScale+ FPGA, and an embedded AMD Zynq UltraScale+ SoC. [...]

The status of\\the CMS Muon Drift Tubes HL-LHC Upgrade and\\the Safety System for the new front-end / De Remigis, Paolo (INFN, Turin) /CMS Collaboration
To sustain the unprecedented radiation and rates of HL-LHC, the readout and trigger electronics for the Drift Tubes (DT) in CMS have been upgraded. The time digitization is implemented on the new OBDT board, and the data are streamed to the new back-end electronics, where event building and trigger primitive generation are performed. The development of a new hardware, called MONitor for SAfety (Monsa) system, monitors and enables each single OBDT. This report provides an update on the status of development and testing of the DT Upgrade electronics, with a focus on the newly introduced safety electronics..

Recent advancements in the tau reconstruction and identification techniques in CMS / Cardini, Andrea (Oviedo U.) /CMS Collaboration
Tau leptons play a crucial role in studies of the Higgs boson and searches for Beyond the Standard Model physics at the present LHC and in its high luminosity upgrade. This talk presents the latest advancements in the reconstruction and identification of hadronic decays of tau leptons at the CMS experiment, both at the online and offline levels. [...]

First observation of tWZ production / Belvedere, Alberto (DESY) /CMS Collaboration
We present the first observation of single top quark production in association with a W and a Z boson in proton-proton collisions using 13 and 13.6 TeV data recorded with the CMS detector corresponding to integrated luminosities of 138 and 61.9 fb-1, respectively. Events are selected if they contain three or four charged leptons, which can be electrons or muons. [...]

Determination of the strong coupling and its running from measurements of inclusive jet production at CMS / Guglielmi, Valentina (Zurich U.) /CMS Collaboration
The value of the strong coupling $\alpha_{S}$ is determined in a comprehensive analysis at next-to-next-to-leading order accuracy in quantum chromodynamics. The analysis uses double-differential cross section measurements from the CMS Collaboration at the CERN LHC of inclusive jet production in proton-proton collisions at centre-of-mass energies of 2.76, 7, 8, and 13\,TeV, combined with inclusive deep-inelastic data from HERA.
