Towards a precise measurements of particles time of flight with the new Mip Timing Detector in the CMS Experiment at High Luminosity of LHC. / Palmeri, Noemi (INFN, Rome ; Rome U.) /CMS Collaboration
The design and primary use cases of the novel MIP Timing Detector (MTD), introduced by the CMS experiment for its High-Luminosity Large Hadron Collider (HL-LHC) Phase-II upgrade, are here described. The strategy for its application to 4D vertex reconstruction is outlined, with a focus on the latest developments in uncertainty estimation. [...]

Innovative Resistive Plate Chambers for the CMS Phase 2 Upgrade Project Summary, Construction, and Quality Assurance / Vandenbroeck, Jules (Gent U.) /CMS Collaboration
In view of the Phase-2 of the LHC physics program, called High Luminosity LHC (HL-LHC), the CMS muon system will be upgraded to maintain a robust muon triggering and reconstruction performance. Therefore RE3/1 and RE4/1 stations of the forward muon system will be equipped with new improved Resistive Plate Chambers (iRPC) as dedicated detectors for muon triggering in CMS. [...]

Combined EFT interpretation of top quark, Higgs boson, electroweak and QCD measurements at CMS / Van Den Bossche, Niels (Gent U.) /CMS Collaboration
A recent EFT result from CMS is presented, combining differential cross section and direct EFT measurements performed by the CMS Collaboration across four branches of the Standard Model: top, Higgs, electroweak and QCD physics. To maximize the sensitivity, measurements of electroweak precision observables from LEP and SLC are included as well. [...]

Rare Decays in CMS / Fedi, Giacomo (Imperial Coll., London) /CMS Collaboration
The CMS experiment at the LHC has advanced precision measurements of rare B-meson and charm decays, offering insights into phenomena beyond the Standard Model (SM). This paper highlights key results from Run 2 and Run 3 data, including the branching fraction and lifetime of $B_s \to \mu^+\mu^- $, angular analyses of $ B^0 \to K^{*0} \mu^+ \mu^- $, the first observation of $ J/\psi \to \mu^+\mu^-\mu^+\mu^- $, and stringent limits on $ D^0 \to \mu^+\mu^- $. [...]

Towards a precise measurement of particles time-of-flight with the new MIP Timing Detector for the CMS Experiment / Palmeri, Noemi (INFN, Rome ; Rome U.) /CMS Collaboration
The MIP Timing Detector (MTD) of the CMS experiment, currently under construction for the High Luminosity phase of LHC, emerges as a key player in the pursuit of unrivaled temporal precision in particle physics.The precise measurement of the time-of-arrival of charged particles provided by the MTD enables the implementation of a 4D vertex reconstruction and helps to discriminate interaction vertices within the same bunch crossing, aiming to recover the vertex cross-contamination levels of the current LHC conditions.In this contribution, we explore the impact of the measured track momentum uncertainty in the time-of-flight determination and its use in the vertex reconstruction and mass hypothesis assignment, shedding light on its potential impact on event reconstruction and classification.The results presented in this abstract demonstrate the efficacy of the MTD in advancing our understanding of particle dynamics in CMS, opening new avenues for an effective usage of precision timing in pileup mitigation and as a tool to probe signatures of new physics with characteristic time structures..
