Operational performance of the CMS Strip Tracker during LHC Run 3 / Sneh Shuchi Sneh /CMS Collaboration
The CMS silicon strip tracker consists of the inner barrel (TIB), inner discs (TID), outer barrel (TOB), and end-cap (TEC) sub-detectors, providing precise measurements for charged particle trajectories up to a pseudorapidity range of $\lvert \eta \rvert < 2.5$. During Run 3 with proton-proton collisions at $\sqrt{s} = 13.6~\mathrm{TeV}$, the CMS strip tracker continues to perform exceedingly well superseding its design goals. [...]

Constraints on anomalous Higgs boson couplings to vector bosons and fermions using the $ \gamma\gamma $ final state in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
Possible anomalous couplings of the Higgs boson to vector bosons and fermions are studied using Higgs boson candidates decaying to a pair of photons. [...]

Search for single vector-like quark production in opposite-sign dilepton final states in proton-proton collisions at $ \sqrt{s}= $ 13 TeV
A search is presented for single production of a vector-like top quark $ \mathrm{T} $, decaying into the standard model top quark and Higgs boson, in a final state including two opposite-sign leptons (electrons or muons), jets, and missing transverse momentum. [...]

Moving tons of fragile crystals with care: the CMS ECAL Enfourneur2 project / Bianco, Roberta (INFN, Rome)
The CMS experiment at the CERN Large Hadron Collider features a high-precision electromagnetic calorimeter (ECAL) made of 61,200 lead tungstate crystals in its central (barrel) part. The crystals are both heavy and fragile, requiring extreme care during handling. [...]
