A search for the standard model Higgs boson decaying to a charm quark-antiquark pair, H→cc¯, produced in association with a top quark-antiquark pair (tt¯H) is presented. The search is performed with data from proton-proton collisions at s=13 TeV, corresponding to an integrated luminosity of 138 fb-1. [...]

A general search is presented for supersymmetric particles (sparticles) in scenarios featuring compressed mass spectra using proton-proton collisions at a center-of-mass energy of 13 TeV, recorded with the CMS detector at the LHC. The analyzed data sample corresponds to an integrated luminosity of 138 fb-1. [...]

A search is presented for a new scalar resonance, X, decaying to a standard model Higgs boson and another new scalar particle, Y, in the final state where the Higgs boson decays to a $\text{b}\overline{\text{b} }$ pair, while the Y particle decays to a pair of photons. The search is performed in the mass range 240–1000 GeV for the resonance X, and in the mass range 70–800 GeV for the particle Y, using proton-proton collision data collected by the CMS experiment at $\sqrt{s}=13$ TeV, corresponding to an integrated luminosity of 132 fb$^{−1}$ [...]

A search for long-lived particles originating from the decay of b hadrons produced in proton-proton collisions with a center-of-mass energy of 13 TeV at the LHC is presented. The analysis is performed on a dataset recorded in 2018, corresponding to an integrated luminosity of 41.6 fb-1. [...]

Using proton-proton collision data collected by the CMS experiment at s=13 TeV in 2016–2018, corresponding to an integrated luminosity of 140 fb-1, the first full reconstruction of the three vector B meson states, B*+, B*0, and Bs*0, is performed. The mass differences between the excited mesons and their corresponding ground states are measured to be m(B*+)-m(B+)=45.277±0.039±0.027 MeV, m(B*0)-m(B0)=45.471±0.056±0.028 MeV, and m(Bs*0)-m(Bs0)=49.407±0.132±0.041 MeV, where the first uncertainties are statistical and the second are systematic.

A search for t-channel exchange of leptoquarks (LQs) is performed in dimuon and dielectron spectra using proton-proton collision data collected at $\sqrt{s}=13$ TeV with the CMS detector at the CERN LHC. The data correspond to an integrated luminosity of 138 fb$^{−1}$ [...]

Measurements are presented of the W and Z boson production cross sections in proton-proton collisions at a center-of-mass energy of 13.6 TeV. Data collected in 2022 and corresponding to an integrated luminosity of 5.01 fb$^{−1}$ with one or two identified muons in the final state are analyzed [...]

The first observation of coherent ϕ(1020) meson photoproduction off heavy nuclei is presented using ultraperipheral lead-lead collisions at a center-of-mass energy per nucleon pair of 5.36 TeV. The data were collected by the CMS experiment and correspond to an integrated luminosity of 1.62 μb−1. [...]

A search for charged-lepton flavour violation (CLFV) in top quark (t) production and decay is presented. The search uses proton-proton collision data corresponding to 138 fb$^{−1}$ collected with the CMS experiment at $\sqrt{s}={13}$ TeV [...]
