Search for natural and split supersymmetry in proton-proton collisions at √s=13 TeV in final states with jets and missing transverse momentum
(2018)Journal of High Energy PhysicsA search for supersymmetry (SUSY) is performed in final states comprising one or more jets and missing transverse momentum using data from proton-proton collisions at a centre-of-mass energy of 13 TeV. The data were recorded with the CMS detector at the CERN LHC in 2016 and correspond to an integrated luminosity of 35.9 fb−1. The number of signal events is found to agree with the expected background yields from standard model processes. ...Journal Article -
Search for a heavy resonance decaying to a pair of vector bosons in the lepton plus merged jet final state at √s=13 TeV
(2018)Journal of High Energy PhysicsA search for a new heavy particle decaying to a pair of vector bosons (WW or WZ) is presented using data from the CMS detector corresponding to an integrated luminosity of 35.9 fb−1 collected in proton-proton collisions at a centre-of-mass energy of 13 TeV in 2016. One of the bosons is required to be a W boson decaying to eν or μν, while the other boson is required to be reconstructed as a single massive jet with substructure compatible ...Journal Article -
Measurement of prompt and nonprompt charmonium suppression in PbPb collisions at 5.02 TeV
(2018)The European Physical Journal CThe nuclear modification factors of J/ψ and ψ(2S) mesons are measured in PbPb collisions at a centre-of-mass energy per nucleon pair of sNN−−−√=5.02TeV. The analysis is based on PbPb and pp data samples collected by CMS at the LHC in 2015, corresponding to integrated luminosities of 464μb−1 and 28pb-1, respectively. The measurements are performed in the dimuon rapidity range of |y|<2.4 as a function of centrality, rapidity, and transverse ...Journal Article -
Search for single production of vector-like quarks decaying to a b quark and a Higgs boson
(2018)Journal of High Energy PhysicsA search is presented for single production of heavy vector-like quarks (B) that decay to a Higgs boson and a b quark, with the Higgs boson decaying to a highly boosted bb¯¯¯ pair reconstructed as a single collimated jet. The analysis is based on data collected by the CMS experiment in proton-proton collisions at s√=13 TeV, corresponding to an integrated luminosity of 35.9 fb−1. The data are consistent with background expectations, and ...Journal Article -
Search for Heavy Neutral Leptons in Events with Three Charged Leptons in Proton-Proton Collisions at s =13 TeV
(2018)Physical Review LettersA search for a heavy neutral lepton N of Majorana nature decaying into a W boson and a charged lepton is performed using the CMS detector at the LHC. The targeted signature consists of three prompt charged leptons in any flavor combination of electrons and muons. The data were collected in proton-proton collisions at a center-of-mass energy of 13 TeV, with an integrated luminosity of 35.9 fb−1. The search is performed in the N mass range ...Journal Article -
Observation of Electroweak Production of Same-Sign W Boson Pairs in the Two Jet and Two Same-Sign Lepton Final State in Proton-Proton Collisions at root s=13 TeV
(2018)Physical Review LettersThe first observation of electroweak production of same-sign W boson pairs in proton-proton collisions is reported. The data sample corresponds to an integrated luminosity of 35.9 fb−1 collected at a center-of-mass energy of 13 TeV with the CMS detector at the LHC. Events are selected by requiring exactly two leptons (electrons or muons) of the same charge, moderate missing transverse momentum, and two jets with a large rapidity ...Journal Article -
Search for a new scalar resonance decaying to a pair of Z bosons in proton-proton collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsA search for a new scalar resonance decaying to a pair of Z bosons is performed in the mass range from 130 GeV to 3 TeV, and for various width scenarios. The analysis is based on proton-proton collisions recorded by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb−1 at a center-of-mass energy of 13 TeV. The Z boson pair decays are reconstructed using the 4ℓ, 2ℓ2q, and 2ℓ2ν final states, where ℓ ...Journal Article -

(2018)Journal of High Energy PhysicsA search for charged Higgs boson decaying to a charm and a bottom quark (H+→cb̄) is performed using 19.7 fb−1 of pp collision data at √s=8 TeV. The production mechanism investigated in this search is tt̄ pair production in which one top quark decays to a charged Higgs boson and a bottom quark and the other decays to a charged lepton, a neutrino, and a bottom quark. Charged Higgs boson decays to cb̄ are searched for, resulting in a final ...Journal Article
