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^- $. [...]
