Search for supersymmetry using Higgs boson to diphoton decays at √s = 13 TeV
(2019)Journal of High Energy PhysicsA search for supersymmetry (SUSY) is presented where at least one Higgs boson is produced and decays to two photons in the decay chains of pair-produced SUSY particles. Two analysis strategies are pursued: one focused on strong SUSY production and the other focused on electroweak SUSY production. The presence of charged leptons, additional Higgs boson candidates, and various kinematic variables are used to categorize events into search ...Journal Article -
Search for anomalous triple gauge couplings in WW and WZ production in lepton + jet events in proton-proton collisions at √s = 13 TeV
(2019)Journal of High Energy PhysicsA search is presented for three additional operators that would lead to anomalous WWγ or WWZ couplings with respect to those in the standard model. They are constrained by studying events with two vector bosons; a W boson decaying to eν or μν, and a W or Z boson decaying hadronically, reconstructed as a single, massive, large- radius jet. The search uses a data set of proton-proton collisions at a centre-of-mass energy of 13 TeV, recorded ...Journal Article -
Measurements of differential Z boson production cross sections in proton-proton collisions at √s = 13 TeV
(2019)Journal of High Energy PhysicsMeasurements are presented of the differential cross sections for Z bosons produced in proton-proton collisions at s√ = 13 TeV and decaying to muons and electrons. The data analyzed were collected in 2016 with the CMS detector at the LHC and correspond to an integrated luminosity of 35.9 fb−1. The measured fiducial inclusive product of cross section and branching fraction agrees with next-to-next-to-leading order quantum chromodynamics ...Journal Article -
Search for a charged Higgs boson decaying into top and bottom quarks in events with electrons or muons in proton-proton collisions at √s = 13 TeV
(2020)Journal of High Energy PhysicsA search is presented for a charged Higgs boson heavier than the top quark, produced in association with a top quark, or with a top and a bottom quark, and decaying into a top-bottom quark-antiquark pair. The search is performed using proton-proton collision data collected by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1. Events are selected by the presence of a ...Journal Article -
Search for top squark pair production in a final state with two tau leptons in proton-proton collisions at √s = 13 TeV
(2020)Journal of High Energy PhysicsA search for pair production of the supersymmetric partner of the top quark, the top squark, in proton-proton collision events at s√ = 13 TeV is presented in a final state containing hadronically decaying tau leptons and large missing transverse momentum. This final state is highly sensitive to high-tan β or higgsino-like scenarios in which decays of electroweak gauginos to tau leptons are dominant. The search uses a data set corresponding ...Journal Article -
Search for dark matter particles produced in association with a Higgs boson in proton-proton collisions at √s = 13 TeV
(2020)Journal of High Energy PhysicsA search for dark matter (DM) particles is performed using events with a Higgs boson candidate and large missing transverse momentum. The analysis is based on proton- proton collision data at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb−1. The search is performed in five Higgs boson decay channels: h→bb⎯⎯⎯, γγ, τ+τ−, W+W−, and ZZ. The results ...Journal Article -
Search for a heavy Higgs boson decaying to a pair of W bosons in proton-proton collisions at √s = 13 TeV
(2020)Journal of High Energy PhysicsA search for a heavy Higgs boson in the mass range from 0.2 to 3.0 TeV, decaying to a pair of W bosons, is presented. The analysis is based on proton-proton collisions at 𝑠��√ = 13 TeV recorded by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb−1. The W boson pair decays are reconstructed in the 2ℓ2ν and ℓν2q final states (with ℓ = e or μ). Both gluon fusion and vector boson fusion production ...Journal Article -
Bose-Einstein correlations of charged hadrons in proton-proton collisions at √s = 13 TeV
(2020)Journal of High Energy PhysicsBose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at 𝑠�√ = 13 TeV. The results are based on data collected using the CMS detector at the LHC during runs with a special low-pileup configuration. Three analysis techniques with different degrees of dependence on simulations are used to remove the ...Journal Article -
Measurement of the top quark pair production cross section in dilepton final states containing one τ lepton in pp collisions at √s= 13 TeV
(2020)Journal of High Energy PhysicsThe cross section of top quark pair production is measured in the tt¯→(ℓνℓ)(τhντ)bb¯ final state, where τh refers to the hadronic decays of the τ lepton, and ℓ is either an electron or a muon. The data sample corresponds to an integrated luminosity of 35.9 fb−1 collected in proton-proton collisions at s = 13 TeV with the CMS detector. The measured cross section is σt t ¯ = 781 ± 7 (stat) ± 62 (syst) ± 20 (lumi) pb, and the ratio of the ...Journal Article -
Search for a heavy pseudoscalar Higgs boson decaying into a 125 GeV Higgs boson and a Z boson in final states with two tau and two light leptons at √s = 13 TeV
(2020)Journal of High Energy PhysicsA search is performed for a pseudoscalar Higgs boson, A, decaying into a 125 GeV Higgs boson h and a Z boson. The h boson is specifically targeted in its decay into a pair of tau leptons, while the Z boson decays into a pair of electrons or muons. A data sample of proton-proton collisions collected by the CMS experiment at the LHC at 𝑠�√ = 13 TeV is used, corresponding to an integrated luminosity of 35.9 fb−1. No excess above the standard ...Journal Article
