Observation of the Bc+ Meson in Pb-Pb and pp Collisions at √sNN=5.02 TeV and Measurement of its Nuclear Modification Factor
(2022)Physical Review LettersThe Bc+ meson is observed for the first time in heavy ion collisions. Data from the CMS detector are used to study the production of the Bc+ meson in lead-lead (Pb-Pb) and proton-proton (pp) collisions at a center-of-mass energy per nucleon pair of sNN=5.02 TeV, via the Bc+→(J/ψ→μ+μ-)μ+νμ decay. The Bc+ nuclear modification factor, derived from the Pb-Pb-to-pp ratio of production cross sections, is measured in two bins of the trimuon ...Journal Article -
Analysis of the CP structure of the Yukawa coupling between the Higgs boson and τ leptons in proton-proton collisions at √s = 13 TeV
(2022)Journal of High Energy PhysicsThe first measurement of the CP structure of the Yukawa coupling between the Higgs boson and tau leptons is presented. The measurement is based on data collected in proton-proton collisions at root s = 13 TeV by the CMS detector at the LHC, corresponding to an integrated luminosity of 137 fb(-1). The analysis uses the angular correlation between the decay planes of tau leptons produced in Higgs boson decays. The effective mixing angle ...Journal Article -
Inclusive nonresonant multilepton probes of new phenomena at √s =13 TeV
(2022)Physical Review DAn inclusive search for nonresonant signatures of beyond the standard model (SM) phenomena in events with three or more charged leptons, including hadronically decaying τ leptons, is presented. The analysis is based on a data sample corresponding to an integrated luminosity of 138 fb-1 of proton-proton collisions at s=13 TeV, collected by the CMS experiment at the LHC in 2016-2018. Events are categorized based on the lepton and b-tagged ...Journal Article -
Search for charged-lepton flavor violation in top quark production and decay in pp collisions at √s=13 TeV
(2022)Journal of High Energy PhysicsResults are presented from a search for charged-lepton flavor violating (CLFV) interactions in top quark production and decay in pp collisions at a center-of-mass energy of 13 TeV. The events are required to contain one oppositely charged electron-muon pair in the final state, along with at least one jet identified as originating from a bottom quark. The data correspond to an integrated luminosity of 138 fb−1, collected by the CMS experiment ...Journal Article -

Search for invisible decays of the Higgs boson produced via vector boson fusion in proton-proton collisions at √s = 13 TeV
(2022)Physical Review DA search for invisible decays of the Higgs boson produced via vector boson fusion (VBF) has been performed with 101 fb(-1) of proton-proton collisions delivered by the LHC at root s = 13 TeV and collected by the CMS detector in 2017 and 2018. The sensitivity to the VBF production mechanism is enhanced by constructing two analysis categories, one based on missing transverse momentum and a second based on the properties of jets. In addition ...Journal Article -

Search for long-lived particles decaying into muon pairs in proton-proton collisions at √s=13 TeV collected with a dedicated high-rate data stream
(2022)Journal of High Energy PhysicsA search for long-lived particles decaying into muon pairs is performed using proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the CMS experiment at the LHC in 2017 and 2018, corresponding to an integrated luminosity of 101 fb(-1). The data sets used in this search were collected with a dedicated dimuon trigger stream with low transverse momentum thresholds, recorded at high rate by retaining a reduced amount ...Journal Article -
Search for a heavy resonance decaying into a top quark and a W boson in the lepton plus jets final state at √s=13 TeV
(2022)Journal of High Energy PhysicsA search for a heavy resonance decaying into a top quark and a W boson in proton-proton collisions at √s = 13 TeV is presented. The data analyzed were recorded with the CMS detector at the LHC and correspond to an integrated luminosity of 138 fb−1. The top quark is reconstructed as a single jet and the W boson, from its decay into an electron or muon and the corresponding neutrino. A top quark tagging technique based on jet clustering ...Journal Article
