Measurement of the pp to ZZ production cross section and constraints on anomalous triple gauge couplings in four-lepton final states at √s = 8 TeV
(2015)Physics Letters BA measurement of the inclusive ZZ production cross section and constraints on anomalous triple gauge couplings in proton-proton collisions at s=8 TeV are presented. The analysis is based on a data sample, corresponding to an integrated luminosity of 19.6fb -1, collected with the CMS experiment at the LHC. The measurements are performed in the leptonic decay modes ZZ→ℓℓℓ ' ℓ ', where ℓ = e, μ and ℓ ' = e, μ, τ. The measured total cross ...Journal Article -
Search for Supersymmetry at the LHC in Events with Jets and Missing Transverse Energy
(2011)Physical Review LettersA search for events with jets and missing transverse energy is performed in a data sample of pp collisions collected at √s=7 TeV by the CMS experiment at the LHC. The analyzed data sample corresponds to an integrated luminosity of 1.14 fb−1. In this search, a kinematic variable αT is used as the main discriminator between events with genuine and misreconstructed missing transverse energy. No excess of events over the standard model ...Journal Article -
Search for New Physics with a Monojet and Missing Transverse Energy in pp Collisions at √s=7 TeV
(2011)Physical Review LettersA study of events with missing transverse energy and an energetic jet is performed using pp collision data at a center-of-mass energy of 7 TeV. The data were collected by the CMS detector at the LHC, and correspond to an integrated luminosity of 36 pb−1. An excess of these events over standard model contributions is a signature of new physics such as large extra dimensions and unparticles. The number of observed events is in good agreement ...Journal Article -
Search for pair production of third-generation scalar leptoquarks and top squarks in proton-proton collisions at √s = 8 TeV
(2014)Physics Letters BA search for pair production of third-generation scalar leptoquarks and supersymmetric top quark partners, top squarks, in final states involving tau leptons and bottom quarks is presented. The search uses events from a data sample of proton–proton collisions corresponding to an integrated luminosity of 19.7 fb−1, collected with the CMS detector at the LHC with s=8 TeV. The number of observed events is found to be in agreement with the ...Journal Article -
Search for a non-standard-model Higgs boson decaying to a pair of new light bosons in four-muon final states
(2013)Physics Letters BResults are reported from a search for non-standard-model Higgs boson decays to pairs of new light bosons, each of which decays into the μ+μ- final state. The new bosons may be produced either promptly or via a decay chain. The data set corresponds to an integrated luminosity of 5.3 fb-1 of proton-proton collisions at s=7 TeV, recorded by the CMS experiment at the LHC in 2011. Such Higgs boson decays are predicted in several scenarios of ...Journal Article -
Study of B Meson Production in p+Pb Collisions at √sNN = 5.02 TeV Using Exclusive Hadronic Decays
(2016)Physical Review LettersThe production cross sections of the B+, B0, and B0s mesons, and of their charge conjugates, are measured via exclusive hadronic decays in p+Pb collisions at the center-of-mass energy √sNN=5.02 TeV with the CMS detector at the CERN LHC. The data set used for this analysis corresponds to an integrated luminosity of 34.6 nb−1. The production cross sections are measured in the transverse momentum range between 10 and 60 GeV/c. No significant ...Journal Article -
Search for physics beyond the standard model using multilepton signatures in pp collisions at root s=7 TeV
(2011)Physics Letters BA search for physics beyond the standard model in events with at least three leptons and any number of jets is presented. The data sample corresponds to 35 pb−1 of integrated luminosity in pp collisions at s=7TeV collected by the CMS experiment at the LHC. A number of exclusive multileptonic channels are investigated and standard model backgrounds are suppressed by requiring sufficient missing transverse energy, invariant mass ...Journal Article -
Measurement of the Polarization of W Bosons with Large Transverse Momenta in W plus jets Events at the LHC
(2011)Physical Review LettersA first measurement of the polarization of W bosons with large transverse momenta in pp collisions is presented. The measurement is based on 36 pb−1 of data recorded at √s=7 TeV by the CMS detector at the LHC. The left-handed, right-handed, and longitudinal polarization fractions (fL, fR, and f0, respectively) of W bosons with transverse momenta larger than 50 GeV are determined by using decays to both electrons and muons. The muon final ...Journal Article -
Search for New Physics with Same-Sign Isolated Dilepton Events with Jets and Missing Transverse Energy
(2012)Physical ReviewA search for new physics is performed in events with two same-sign isolated leptons, hadronic jets, and missing transverse energy in the final state. The analysis is based on a data sample corresponding to an integrated luminosity of 4.98 fb−1 produced in pp collisions at a center-of-mass energy of 7 TeV collected by the CMS experiment at the LHC. This constitutes a factor of 140 increase in integrated luminosity over previously published ...Journal Article -
Determination of the top-quark pole mass and strong coupling constant from the tt¯ production cross section in pp collisions at √s = 7 TeV
(2014)Physics Letters BThe inclusive cross section for top-quark pair production measured by the CMS experiment in proton–proton collisions at a center-of-mass energy of 7 TeV is compared to the QCD prediction at next-to-next-to-leading order with various parton distribution functions to determine the top-quark pole mass, mt pole, or the strong coupling constant, αS. With the parton distribution function set NNPDF2.3, a pole mass of 176.7−3.4 +3.8 GeV is obtained ...Journal Article
