Search for resonant and nonresonant Higgs boson pair production in the bbℓνℓν final state in proton-proton collisions at s√=13 TeV
(2018)Journal of High Energy PhysicsSearches for resonant and nonresonant pair-produced Higgs bosons (HH) decaying respectively into ℓνℓν, through either W or Z bosons, and \( \mathrm{b}\overline{\mathrm{b}} \) are presented. The analyses are based on a sample of proton-proton collisions at \( \sqrt{s}=13 \) TeV, collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb−1. Data and predictions from the standard model are in agreement ...Journal Article -
Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks
(2018)Physical Review DA search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance pmissT in transverse momentum. The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, and correspond to an integrated luminosity of 35.9 fb−1. Search regions are defined in terms of the multiplicity of bottom quark jet and top quark ...Journal Article -
Observation of top quark production in proton-nucleus collisions
(2017)Physical Review LettersThe first observation of top quark production in proton-nucleus collisions is reported using proton-lead data collected by the CMS experiment at the CERN LHC at a nucleon-nucleon center-of-mass energy of √sNN=8.16 TeV. The measurement is performed using events with exactly one isolated electron or muon candidate and at least four jets. The data sample corresponds to an integrated luminosity of 174 nb−1. The significance of the t¯t signal ...Journal Article -
Constraints on anomalous Higgs boson couplings using production and decay information in the four-lepton final state
(2017)Physics Letters BA search is performed for anomalous interactions of the recently discovered Higgs boson using matrix element techniques with the information from its decay to four leptons and from associated Higgs boson production with two quark jets in either vector boson fusion or associated production with a vector boson. The data were recorded by the CMS experiment at the LHC at a center-of-mass energy of and correspond to an integrated luminosity ...Journal Article -
Search for dark matter produced in association with heavy-flavor quark pairs in proton-proton collisions at √s=13TeV
(2017)The European Physical Journal CA search is presented for an excess of events with heavy-flavor quark pairs (tt¯ and bb¯¯) and a large imbalance in transverse momentum in data from proton–proton collisions at a center-of-mass energy of 13TeV. The data correspond to an integrated luminosity of 2.2fb−1 collected with the CMS detector at the CERN LHC. No deviations are observed with respect to standard model predictions. The results are used in the first interpretation of ...Journal Article -
Search for Evidence of the Type-III Seesaw Mechanism in Multilepton Final States in Proton-Proton Collisions at √s=13 TeV
(2017)Physical Review LettersA search for a signal consistent with the type-III seesaw mechanism in events with three or more electrons or muons is presented. The data sample consists of proton-proton collisions at √s=13 TeV collected by the CMS experiment at the LHC in 2016 and corresponds to an integrated luminosity of 35.9 fb−1. Selection criteria based on the number of leptons and the invariant mass of oppositely charged lepton pairs are used to distinguish the ...Journal Article -
Search for supersymmetry in events with at least one photon, missing transverse momentum, and large transverse event activity in proton-proton collisions at √s=13 TeV
(2017)Journal of High Energy PhysicsA search for physics beyond the standard model in final states with at least one photon, large transverse momentum imbalance, and large total transverse event activity is presented. Such topologies can be produced in gauge-mediated supersymmetry models in which pair-produced gluinos or squarks decay to photons and gravitinos via short-lived neutralinos. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton-proton ...Journal Article -
Measurement of charged pion, kaon, and proton production in proton-proton collisions at √s=13 TeV
(2017)Physical Review DTransverse momentum spectra of charged pions, kaons, and protons are measured in proton-proton collisions at √s=13 TeV with the CMS detector at the LHC. The particles, identified via their energy loss in the silicon tracker, are measured in the transverse momentum range of pT≈0.1–1.7 GeV/c and rapidities |y|<1. The pT spectra and integrated yields are compared to previous results at smaller √s and to predictions of Monte Carlo event ...Journal Article -
Search for black holes and other new phenomena in high-multiplicity final states in proton–proton collisions at √s = 13 TeV
(2017)Physics Letters BA search for new physics in energetic, high-multiplicity final states has been performed using proton–proton collision data collected with the CMS detector at a center-of-mass energy of 13TeV and corresponding to an integrated luminosity of 2.3fb-1. The standard model background, dominated by multijet production, is determined exclusively from control regions in data. No statistically significant excess of events is observed. Model-independent ...Journal Article -
Combination of searches for heavy resonances decaying to WW, WZ, ZZ, WH, and ZH boson pairs in proton–proton collisions at s√=8 and 13 TeV
(2017)Physics Letters BA statistical combination of searches is presented for massive resonances decaying to WW, WZ, ZZ, WH, and ZH boson pairs in proton-proton collision data collected by the CMS experiment at the LHC. The data were taken at centre-of-mass energies of 8 and 13TeV, corresponding to respective integrated luminosities of 19.7 and up to 2.7 fb(-1). The results are interpreted in the context of heavy vector triplet and singlet models that mimic ...Journal Article
