Search for the X(5568) State Decaying into B0sπ± in Proton-Proton Collisions at √s=8 TeV
(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 -
Observation of ttH Production
(2018)Physical Review LettersThe observation of Higgs boson production in association with a top quark-antiquark pair is reported, based on a combined analysis of proton-proton collision data at center-of-mass energies of √s=7, 8, and 13 TeV, corresponding to integrated luminosities of up to 5.1, 19.7, and 35.9 fb−1, respectively. The data were collected with the CMS detector at the CERN LHC. The results of statistically independent searches for Higgs bosons produced ...Journal Article -

Search for high-mass resonances in final states with a lepton and missing transverse momentum at √s=13 TeV
(2018)Journal of High Energy PhysicsA search for new high-mass resonances in proton-proton collisions having final states with an electron or muon and missing transverse momentum is presented. The analysis uses proton-proton collision data collected in 2016 with the CMS detector at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1. The transverse mass distribution of the charged lepton-neutrino system is used as the ...Journal Article -
Search for disappearing tracks as a signature of new long-lived particles in proton-proton collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsA search is presented for long-lived charged particles that decay within the CMS detector and produce the signature of a disappearing track. A disappearing track is an isolated track with missing hits in the outer layers of the silicon tracker, little or no energy in associated calorimeter deposits, and no associated hits in the muon detectors. This search uses data collected with the CMS detector in 2015 and 2016 from proton-proton ...Journal Article -
Search for resonant pair production of Higgs bosons decaying to bottom quark-antiquark pairs in proton-proton collisions at 13 TeV
(2018)Journal of High Energy PhysicsA search for a narrow-width resonance decaying into two Higgs bosons, each decaying into a bottom quark-antiquark pair, is presented. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 35.9 fb−1 at s√=13 TeV recorded by the CMS detector at the LHC. No evidence for such a signal is observed. Upper limits are set on the product of the production cross section for the resonance and the ...Journal Article -
Search for beyond the standard model Higgs bosons decaying into a b b ¯ pair in pp collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsA search for Higgs bosons that decay into a bottom quark-antiquark pair and are accompanied by at least one additional bottom quark is performed with the CMS detector. The data analyzed were recorded in proton-proton collisions at a centre-of-mass energy of s√=13 TeV at the LHC, corresponding to an integrated luminosity of 35.7 fb−1. The final state considered in this analysis is particularly sensitive to signatures of a Higgs sector ...Journal Article -
Measurement of the cross section for top quark pair production in association with a W or Z boson in proton-proton collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsA measurement is performed of the cross section of top quark pair production in association with a W or Z boson using proton-proton collisions at a center-of-mass energy of 13 TeV at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb−1, collected by the CMS experiment in 2016. The measurement is performed in the same-sign dilepton, three- and four-lepton final states. The production cross sections are measured to ...Journal Article -
Search for a heavy resonance decaying into a Z boson and a vector boson in the νν¯qq¯ final state
(2018)Journal of High Energy PhysicsA search is presented for a heavy resonance decaying into either a pair of Z bosons or a Z boson and a W boson (ZZ or WZ), with a Z boson decaying into a pair of neutrinos and the other boson decaying hadronically into two collimated quarks that are reconstructed as a highly energetic large-cone jet. The search is performed using the data collected with the CMS detector at the CERN LHC during 2016 in proton-proton collisions at a ...Journal Article -
Search for a singly produced third-generation scalar leptoquark decaying to a τ lepton and a bottom quark in proton-proton collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsA search is presented for a singly produced third-generation scalar leptoquark decaying to a τ lepton and a bottom quark. Associated production of a leptoquark and a τ lepton is considered, leading to a final state with a bottom quark and two τ leptons. The search uses proton-proton collision data at a center-of-mass energy of 13 TeV recorded with the CMS detector, corresponding to an integrated luminosity of 35.9 fb−1. Upper limits are ...Journal Article
