Measurements of the differential cross sections of the production of Z + jets and γ + jets and of Z boson emission collinear with a jet in pp collisions at √s = 13 TeV
(2021)Journal of High Energy PhysicsMeasurements of the differential cross sections of Z + jets and γ + jets production, and their ratio, are presented as a function of the boson transverse momentum. Measurements are also presented of the angular distribution between the Z boson and the closest jet. The analysis is based on pp collisions at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 35.9 fb−1 recorded by the CMS experiment at the LHC. The ...Journal Article -
Search for nonresonant Higgs boson pair production in final states with two bottom quarks and two photons in proton-proton collisions at √s = 13 TeV
(2021)Journal of High Energy PhysicsA search for nonresonant production of Higgs boson pairs via gluon-gluon and vector boson fusion processes in final states with two bottom quarks and two photons is presented. The search uses data from proton-proton collisions at a center-of-mass energy of 𝑠��√ = 13 TeV recorded with the CMS detector at the LHC, corresponding to an integrated luminosity of 137 fb−1. No significant deviation from the background-only hypothesis is observed. ...Journal Article -
Search for the lepton flavor violating decay τ → 3μ in proton-proton collisions at √s = 13 TeV
(2021)Journal of High Energy PhysicsResults are reported from a search for the lepton flavor violating decay τ → 3μ in proton-proton collisions at s√ = 13 TeV. The data sample corresponds to an integrated luminosity of 33.2 fb−1 recorded by the CMS experiment at the LHC in 2016. The search exploits τ leptons produced in both W boson and heavy-flavor hadron decays. No significant excess above the expected background is observed. An upper limit on the branching fraction ℬ(τ ...Journal Article -
Evidence for Higgs boson decay to a pair of muons
(2021)Journal of High Energy PhysicsEvidence for Higgs boson decay to a pair of muons is presented. This result combines searches in four exclusive categories targeting the production of the Higgs boson via gluon fusion, via vector boson fusion, in association with a vector boson, and in association with a top quark-antiquark pair. The analysis is performed using proton-proton collision data at 𝑠��√ = 13 TeV, corresponding to an integrated luminosity of 137 fb−1, recorded ...Journal Article -
Measurement of the inclusive and differential Higgs boson production cross sections in the leptonic WW decay mode at √s = 13 TeV
(2021)Journal of High Energy PhysicsMeasurements of the fiducial inclusive and differential production cross sections of the Higgs boson in proton-proton collisions at s = 13 TeV are performed using events where the Higgs boson decays into a pair of W bosons that subsequently decay into a final state with an electron, a muon, and a pair of neutrinos. The analysis is based on data collected with the CMS detector at the LHC during 2016–2018, corresponding to an integrated ...Journal Article -
Search for new physics in top quark production with additional leptons in proton-proton collisions at √s = 13 TeV using effective field theory
(2021)Journal of High Energy PhysicsEvents containing one or more top quarks produced with additional prompt leptons are used to search for new physics within the framework of an effective field theory (EFT). The data correspond to an integrated luminosity of 41.5 fb−1 of proton-proton collisions at a center-of-mass energy of 13 TeV at the LHC, collected by the CMS experiment in 2017. The selected events are required to have either two leptons with the same charge or more ...Journal Article -
