 Improved Resistive Plate Chambers for Phase 2 upgrade of CMS / Samalan, Amrutha (Gent U.) In view of the High Luminosity LHC, the CMS Muon system will be upgraded to sustain its efficient muon triggering and reconstruction performance. Resistive Plate Chambers (RPC) serve as dedicated detectors for muon triggering due to their excellent timing resolution. [...] CMS-CR-2022-223.- Geneva : CERN, 2022 - 7 p.

 The CMS RPC system readiness for LHC Run 3 data taking / Shopova, Mariana (Sofiya, Inst. Nucl. Res.) /CMS Collaboration During Run-3, the LHC is preparing to deliver instantaneous luminosity in the range from 5 x 10$^{34}$ cm$^{-2}$s$^{-1}$ to 7.5 x 10$^{34}$ cm$^{-2}$s$^{-1}$. To ensure stable data taking, providing redundant information for robust muon triggering, reconstruction and identification, the CMS RPC collaboration has used the opportunity given by the LHC long shutdown 2 (LS2), to perform a series of maintenance and preparation activities for the new data taking period.

 RPC based tracking system at CERN GIF++ facility / Mota Amarilo, Kevin (Rio de Janeiro State U.) /CMS Collaboration With the HL-LHC upgrade of the LHC machine, an increase of the instantaneous luminosity by a factor of five is expected and the current detection systems need to be validated for such working conditions to ensure stable data taking. At the CERN Gamma Irradiation Facility (GIF++) many muon detectors undergo such studies, but the high gamma background can pose a challenge to the muon trigger system which is exposed to many fake hits from the gamma background.

 Studies of top quark properties in CMS / Schwarz, Dennis (Vienna, OAW) /CMS Collaboration In this article, recent studies of top quark properties in CMS are presented. The discussed analyses are measurements of the charge asymmetry, CP violation and jet mass, all carried out in final states of tt production with one or two leptons.

 Triggering on electrons, photons, tau leptons, jets and energy sums at HL-LHC with the upgraded CMS Level-1 Trigger / Meiring, Peter Eduard (Zurich U.) /CMS Collaboration The High-Luminosity LHC (HL-LHC) will open an unprecedented window on the weak-scale nature of the universe, providing high-precision measurements of the standard model as well as searches for new physics beyond the standard model. The CMS experiment is planning to replace entirely its trigger and data acquisition system to achieve this ambitious physics program. [...] CMS-CR-2022-237.- Geneva : CERN, 2022 - 5 p.

 Level-1 Track Quality Evaluation at CMS for the HL-LHC / Savard, Claire (Colorado U.) /CMS Collaboration The upcoming High-Luminosity LHC will provide 200 proton-proton collisions per bunch crossing on average, thus creating highly complex events demanding efficient data reconstruction and processing. In order to meet these requirements, the CMS experiment is upgrading its Level-1 trigger system. [...] CMS-CR-2022-236.- Geneva : CERN, 2022 - 5 p.

 Overview of the HL-LHC Upgrade for the CMS Level-1 Trigger / Radburn-smith, Benjamin Charles (Imperial Coll., London) /CMS Collaboration High-precision measurements of the standard model as well as searches for new physics beyond the standard model require the statistical power of the High-Luminosity LHC. The CMS experiment will perform an upgrade of the Level-1 hardware trigger in order to take full advantage of the High-Luminosity LHC. [...] CMS-CR-2022-232.- Geneva : CERN, 2022 - 7 p.

 Recent results on femtoscopic correlations with the CMS experiment / Bernardes, Cesar Augusto (SAO_PAULO) /CMS Collaboration The study of femtoscopic correlations in high-energy collisions is a powerful tool to investigate the space-time structure of the particle emitting region formed in such collisions, as well as to probe interactions that the involved particles may undergo after being emitted. An overview of the recent results on the two-particle femtoscopic correlations measurements using charged particles and identified hadrons in pp, pPb, and PbPb collisions at LHC energies is presented.

 Upgrade of the Drift Tube (DT) Muon System for the CMS Detector at the HL-LHC / Kiani, Muhammad Bilal (INFN, Turin ; Turin U.) /CMS Collaboration The High-Luminosity Large Hadron Collider (HL-LHC) project aims to boost the performance of the LHC, augmenting the potential for discoveries and the accuracy of SM measurements. From the LHC Run-4 onwards, the upgrade aims at increasing the instantaneous luminosity of the machine, to target an overall ten-fold increase of the collected dataset compared to the LHC initial design.
