Search for higgsinos decaying to two Higgs bosons and missing transverse momentum in proton-proton collisions at √s=13 TeV
(2022)Journal of High Energy PhysicsResults are presented from a search for physics beyond the standard model in proton-proton collisions at root s = 13 TeV in channels with two Higgs bosons, each decaying via the process H -> b (b) over bar, and large missing transverse momentum. The search uses a data sample corresponding to an integrated luminosity of 137fb(-1) collected by the CMS experiment at the CERN LHC. The search is motivated by models of supersymmetry that predict ...Journal Article -
Search for supersymmetry in final states with two or three soft leptons and missing transverse momentum in proton-proton collisions at s√ = 13 TeV
(2022)Journal of High Energy PhysicsA search for supersymmetry in events with two or three low-momentum leptons and missing transverse momentum is performed. The search uses proton-proton collisions at root s = 13TeV collected in the three-year period 2016-2018 by the CMS experiment at the LHC and corresponding to an integrated luminosity of up to 137 fb(-1). The data are found to be in agreement with expectations from standard model processes. The results are interpreted ...Journal Article -
Search for a heavy resonance decaying to a top quark and a W boson at s√ = 13 TeV in the fully hadronic final state
(2021)Journal of High Energy PhysicsA search for a heavy resonance decaying to a top quark and a W boson in the fully hadronic final state is presented. The analysis is performed using data from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 137 fb(-1) recorded by the CMS experiment at the LHC. The search is focused on heavy resonances, where the decay products of each top quark or W boson are expected to be ...Journal Article -
Search for flavor-changing neutral current interactions of the top quark and the Higgs boson decaying to a bottom quark-antiquark pair at s√ = 13 TeV
(2022)Journal of High Energy PhysicsA search for flavor-changing neutral current interactions of the top quark (t) and the Higgs boson (H) is presented. The search is based on a data sample corresponding to an integrated luminosity of 137 fb(-1) recorded by the CMS experiment at the LHC in proton-proton collisions at root s = 13TeV. Events containing exactly one lepton (muon or electron) and at least three jets, among which at least two are identified as originating from ...Journal Article -
Search for electroweak production of charginos and neutralinos in proton-proton collisions at s√ = 13 TeV
(2022)Journal of High Energy PhysicsA direct search for electroweak production of charginos and neutralinos is presented. Events with three or four leptons, with up to two hadronically decaying tau leptons, or two same-sign light leptons are analyzed. The data sample consists of 137 fb(-1) of proton-proton collisions with a center of mass energy of 13 TeV, recorded with the CMS detector at the LHC. The results are interpreted in terms of several simplified models. These ...Journal Article -

(2022)Journal of High Energy PhysicsA search is presented for single production of a vector-like T quark with charge 2/3 e, in the decay channel featuring a top quark and a Z boson, with the top quark decaying hadronically and the Z boson decaying to neutrinos. The search uses data collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 137 fb(-1) recorded at the CERN LHC in 2016-2018. ...Journal Article -
Search for heavy resonances decaying to ZZ or ZW and axion-like particles mediating nonresonant ZZ or ZH production at s√ = 13 TeV
(2022)Journal of High Energy PhysicsA search has been performed for heavy resonances decaying to ZZ or ZW and for axion-like particles (ALPs) mediating nonresonant ZZ or ZH production, in final states with two charged leptons (ℓ = e, μ) produced by the decay of a Z boson, and two quarks produced by the decay of a Z, W, or Higgs boson H. The analysis is sensitive to resonances with masses in the range 450 to 2000 GeV. Two categories are defined corresponding to the merged ...Journal Article -
Study of dijet events with large rapidity separation in proton-proton collisions at √s = 2.76 TeV
(2022)Journal of High Energy PhysicsThe cross sections for inclusive and Mueller-Navelet dijet production are measured as a function of the rapidity separation between the jets in proton-proton collisions at s = 2.76 TeV for jets with transverse momentum pT> 35 GeV and rapidity |y| < 4.7. Various dijet production cross section ratios are also measured. A veto on additional jets with pT> 20 GeV is introduced to improve the sensitivity to the effects of the Balitsky-Fadin-K ...Journal Article -
Measurement of the inclusive and differential tt¯ γ cross sections in the dilepton channel and effective field theory interpretation in proton-proton collisions at √s = 13 TeV
(2022)Journal of High Energy PhysicsThe production cross section of a top quark pair in association with a photon is measured in proton-proton collisions in the decay channel with two oppositely charged leptons (e(+/-)mu(-/+), e(+)e(-), or mu(+)mu(-)). The measurement is performed using 138 fb(-1) of proton-proton collision data recorded by the CMS experiment at root s = 13 TeV during the 2016-2018 data-taking period of the CERN LHC. A fiducial phase space is defined such ...Journal Article -
