Measurements of the charm jet cross section and nuclear modification factor in pPb collisions at √sNN = 5.02 TeV
(2017)Physics Letters BThe CMS Collaboration presents the first measurement of the differential cross section of jets from charm quarks produced in proton–lead (pPb) collisions at a nucleon–nucleon center-of-mass energy of √sNN=5.02TeV, as well as results from charm quark jets in proton–proton (pp) collisions at s=2.76 and 5.02TeV. By comparing the yields of the pPb and pp collision systems at the same energy, a nuclear modification factor for charm jets from ...Journal Article -
Search for high-mass Zγ resonances in proton–proton collisions at √s = 8 and 13 TeV using jet substructure techniques
(2017)Physics Letters BA search for massive resonances decaying to a Z boson and a photon is performed in events with a hadronically decaying Z boson candidate, separately in light-quark and b quark decay modes, identified using jet substructure and advanced b tagging techniques. Results are based on samples of proton–proton collisions collected with the CMS detector at the LHC at center-of-mass energies of 8 and 3.0 TeV, corresponding to integrated luminosities ...Journal Article -
Search for standard model production of four top quarks in proton-proton collisions at s√ = 13 TeV
(2017)Physics Letters BA search for events containing four top quarks () is reported from proton–proton collisions recorded by the CMS experiment at and corresponding to an integrated luminosity of 2.6 fb−1. The analysis considers the single-lepton (e or μ)+jets and the opposite-sign dilepton (, , or )+jets channels. It uses boosted decision trees to combine information on the global event and jet properties to distinguish between and production. The number of ...Journal Article -
Search for anomalous couplings in boosted WW/WZ→ℓνqq¯ production in proton-proton collisions at √s = 8 TeV
(2017)Physics Letters BThis Letter presents a search for new physics manifested as anomalous triple gauge boson couplings in WW and WZ diboson production in proton–proton collisions. The search is performed using events containing a W boson that decays leptonically and a W or Z boson whose decay products are merged into a single reconstructed jet. The data, collected at s=8 TeV with the CMS detector at the LHC, correspond to an integrated luminosity of 19 fb−1. ...Journal Article -

Search for heavy resonances that decay into a vector boson and a Higgs boson in hadronic final states at √s=13TeV
(2017)The European Physical Journal CA search for heavy resonances with masses above 1TeV, decaying to final states containing a vector boson and a Higgs boson, is presented. The search considers hadronic decays of the vector boson, and Higgs boson decays to b quarks. The decay products are highly boosted, and each collimated pair of quarks is reconstructed as a single, massive jet. The analysis is performed using a data sample collected in 2016 by the CMS experiment at the ...Journal Article -
Search for new phenomena with multiple charged leptons in proton–proton collisions at √s=13TeV
(2017)The European Physical Journal CResults are reported from a search for physics beyond the standard model in final states with at least three charged leptons, in any combination of electrons or muons. The data sample corresponds to an integrated luminosity of 2.3fb−1 of proton–proton collisions at s√=13TeV, recorded by the CMS experiment at the LHC in 2015. Two jets are required in each event, providing good sensitivity to strong production of gluinos and squarks. The ...Journal Article -
Search for physics beyond the standard model in events with two leptons of same sign, missing transverse momentum, and jets in proton–proton collisions at √s=13TeV
(2017)The European Physical Journal CA data sample of events from proton–proton collisions with two isolated same-sign leptons, missing transverse momentum, and jets is studied in a search for signatures of new physics phenomena by the CMS Collaboration at the LHC. The data correspond to an integrated luminosity of 35.9fb−1, and a center-of-mass energy of 13TeV. The properties of the events are consistent with expectations from standard model processes, and no excess yield ...Journal Article -
Search for a heavy resonance decaying to a top quark and a vector-like top quark at √s=13 TeV
(2017)Journal of High Energy PhysicsA search is presented for massive spin-1 Z′ resonances decaying to a top quark and a heavy vector-like top quark partner T. The search is based on a 2.6 fb−1 sample of proton-proton collisions at 13 TeV collected with the CMS detector at the LHC. The analysis is optimized for final states in which the T quark decays to a W boson and a bottom quark. The focus is on all-jet final states in which both the W boson and the top quark decay into ...Journal Article
