Measurements of Higgs boson production cross sections and couplings in the diphoton decay channel at √s = 13 TeV
(2021)Journal of High Energy PhysicsMeasurements of Higgs boson production cross sections and couplings in events where the Higgs boson decays into a pair of photons are reported. Events are selected from a sample of proton-proton collisions at √s = 13 TeV collected by the CMS detector at the LHC from 2016 to 2018, corresponding to an integrated luminosity of 137 fb−1. Analysis categories enriched in Higgs boson events produced via gluon fusion, vector boson fusion, vector ...Journal Article -
Measurement of the Electron Charge Asymmetry in Inclusive W Production in pp Collisions at √s=7 TeV
(2012)Physical Review LettersA measurement of the electron charge asymmetry in inclusive pp→W+X→eν+X production at √s=7 TeV is presented based on data recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 840 pb−1. The electron charge asymmetry reflects the unequal production of W+ and W− bosons in pp collisions. The electron charge asymmetry is measured in bins of the absolute value of electron pseudorapidity in the range of ...Journal Article -
Measurement of the t-Channel Single Top Quark Production Cross Section in pp Collisions at √s=7 TeV
(2011)Physical Review LettersElectroweak production of the top quark is measured for the first time in pp collisions at √s=7 TeV, using a data set collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 36 pb−1. With an event selection optimized for t-channel production, two complementary analyses are performed. The first one exploits the special angular properties of the signal, together with background estimates from the data. ...Journal Article -
Search for direct production of GeV-scale resonances decaying to a pair of muons in proton-proton collisions √s = 13 TeV
(2023)Journal of High Energy PhysicsA search for direct production of low-mass dimuon resonances is performed using √s = 13 TeV proton-proton collision data collected by the CMS experiment during the 2017–2018 operation of the CERN LHC with an integrated luminosity of 96.6 fb−1. The search exploits a dedicated high-rate trigger stream that records events with two muons with transverse momenta as low as 3 GeV but does not include the full event information. The search is ...Journal Article -
Inclusive b-hadron production cross section with muons in pp collisions at √s=7 TeV
(2011)Journal of High Energy PhysicsA measurement of the b-hadron production cross section in proton-proton collisions at s√=7TeV is presented. The dataset, corresponding to 85 nb−1, was recorded with the CMS experiment at the LHC using a low-threshold single-muon trigger. Events are selected by the presence of a muon with transverse momentum pμT>6GeV with respect to the beam direction and pseudorapidity |η μ | < 2.1. The transverse momentum of the muon with respect to the ...Journal Article -
The CMS trigger system
(2017)Journal of InstrumentationThis paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of potential physics interest from a GHz (MHz) interaction rate of proton-proton (heavy ion) collisions. The first level of the trigger is implemented in hardware, and selects events containing detector signals consistent with an electron, photon, muon, τ lepton, jet, or missing ...Journal Article -

Search for physics beyond the standard model in top quark production with additional leptons in the context of effective field theory
(2023)Journal of High Energy PhysicsA search for new physics in top quark production with additional fnal-state leptons is performed using data collected by the CMS experiment in proton-proton collisions at √ s = 13 TeV at the LHC during 2016–2018. The data set corresponds to an integrated luminosity of 138 fb−1 . Using the framework of efective feld theory (EFT), potential new physics efects are parametrized in terms of 26 dimension-six EFT operators. The impacts of EFT ...Journal Article -
