Measurements of the associated production of a Z boson and b jets in pp collisions at √s = 8 TeV
(2017)The European Physical Journal CMeasurements of the associated production of a Z boson with at least one jet originating from a b quark in proton–proton collisions at √s=8TeV are presented. Differential cross sections are measured with data collected by the CMS experiment corresponding to an integrated luminosity of 19.8fb−1. Z bosons are reconstructed through their decays to electrons and muons. Cross sections are measured as a function of observables characterizing ...Journal Article -
Search for leptophobic Z′ bosons decaying into four-lepton final states in proton–proton collisions at √s=8TeV
(2017)Physics Letters BA search for heavy narrow resonances decaying into four-lepton final states has been performed using proton–proton collision data at √s=8TeV collected by the CMS experiment, corresponding to an integrated luminosity of 19.7fb-1. No excess of events over the standard model background expectation is observed. Upper limits for a benchmark model on the product of cross section and branching fraction for the production of these heavy narrow ...Journal Article -
Search for Higgs boson pair production in the bbττ final state in proton-proton collisions at √(s)=8 TeV
(2017)Physical Review DResults are presented from a search for production of Higgs boson pairs (HH) where one boson decays to a pair of b quarks and the other to a τ lepton pair. This work is based on proton-proton collision data collected by the CMS experiment at √s=8 TeV, corresponding to an integrated luminosity of 18.3 fb−1. Resonant and nonresonant modes of HH production have been probed and no significant excess relative to the background-only hypotheses ...Journal Article -
Search for light bosons in decays of the 125 GeV Higgs boson in proton-proton collisions at √s=8 TeV
(2017)Journal of High Energy PhysicsA search is presented for decays beyond the standard model of the 125 GeV Higgs bosons to a pair of light bosons, based on models with extended scalar sectors. Light boson masses between 5 and 62.5 GeV are probed in final states containing four τ leptons, two muons and two b quarks, or two muons and two τ leptons. The results are from data in proton-proton collisions corresponding to an integrated luminosity of 19.7 fb−1, accumulated by ...Journal Article -
Cross section measurement of t-channel single top quark production in pp collisions at s√= 13 TeV
(2017)Physics Letters BThe cross section for the production of single top quarks in the t channel is measured in proton- proton collisions at 13TeV with the CMS detector at the LHC. The analyzed data correspond to an integrated luminosity of 2.2fb(-1). The event selection requires one muon and two jets where one of the jets is identified as originating from a bottom quark. Several kinematic variables are then combined into a multivariate discriminator to ...Journal Article -
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 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 -
Measurement of the tt¯ production cross section using events with one lepton and at least one jet in pp collisions at s√ = 13 TeV
(2017)Journal of High Energy PhysicsA measurement of the tt¯ production cross section at s√=13 TeV is presented using proton-proton collisions, corresponding to an integrated luminosity of 2.2 fb−1, collected with the CMS detector at the LHC. Final states with one isolated charged lepton (electron or muon) and at least one jet are selected and categorized according to the accompanying jet multiplicity. From a likelihood fit to the invariant mass distribution of the isolated ...Journal Article -
