Measurement of normalized differential tt̄ cross sections in the dilepton channel from pp collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsNormalized differential cross sections for top quark pair production are measured in the dilepton (e+e−, μ+μ−, and μ∓e±) decay channels in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurements are performed with data corresponding to an integrated luminosity of 2.1 fb−1 using the CMS detector at the LHC. The cross sections are measured differentially as a function of the kinematic properties of the leptons, jets ...Journal Article -
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 Higgsino pair production in 𝑝𝑝 collisions at √s=13 TeV in final states with large missing transverse momentum and two Higgs bosons decaying via H→bb̄
(2018)Physical Review DResults are reported from a search for new physics in 13 TeV proton-proton collisions in the final state with large missing transverse momentum and two Higgs bosons decaying via H→b¯b. The search uses a data sample accumulated by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb−1. The search is motivated by models based on gauge-mediated supersymmetry breaking, which predict the electroweak ...Journal Article -
Search for new physics in final states with an energetic jet or a hadronically decaying W or Z boson and transverse momentum imbalance at √s=13 TeV
(2018)Physical Review DA search for new physics using events containing an imbalance in transverse momentum and one or more energetic jets arising from initial-state radiation or the hadronic decay of W or Z bosons is presented. A data sample of proton-proton collisions at √s=13 TeV, collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9 fb−1, is used. The observed data are found to be in agreement with the expectation ...Journal Article -
Jet properties in PbPb and pp collisions at √sNN=5.02 TeV
(2018)Journal of High Energy PhysicsModifications of the properties of jets in PbPb collisions, relative to those in pp collisions, are studied at a nucleon-nucleon center-of-mass energy of sNN−−−−√=5.02 TeV via correlations of charged particles with the jet axis in relative pseudorapidity (Δη), relative azimuth (Δϕ), and relative angular distance from the jet axis Δr=(Δη)2+(Δϕ)2−−−−−−−−−−−−√. This analysis uses data collected with the CMS detector at the LHC, corresponding ...Journal Article -
Search for lepton-flavor violating decays of heavy resonances and quantum black holes to eμ final states in proton-proton collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsA search is reported for heavy resonances decaying into eμ final states in proton-proton collisions recorded by the CMS experiment at the CERN LHC at s√=13 TeV, corresponding to an integrated luminosity of 35.9 fb−1. The search focuses on resonance masses above 200 GeV. With no evidence found for physics beyond the standard model in the eμ mass spectrum, upper limits are set at 95% confidence level on the product of the cross section and ...Journal Article -

(2018)Physical Review LettersA search for resonancelike structures in the B0sπ± invariant mass spectrum is performed using proton-proton collision data collected by the CMS experiment at the LHC at √s=8 TeV, corresponding to an integrated luminosity of 19.7 fb−1. The B0s mesons are reconstructed in the decay chain B0s→J/ψϕ, with J/ψ→μ+μ− and ϕ→K+K−. The B0sπ± invariant mass distribution shows no statistically significant peaks for different selection requirements ...Journal Article -

(2018)Physical Review DA search for new physics is presented in final states with two oppositely charged leptons (electrons or muons), jets identified as originating from b quarks, and missing transverse momentum (pmissT). The search uses proton-proton collision data at √s=13 TeV amounting to 35.9 fb−1 of integrated luminosity collected using the CMS detector in 2016. Hypothetical signal events are efficiently separated from the dominant t¯t background with ...Journal Article -
