Combined results of searches for the standard model Higgs boson in pp collisions at root s=7 TeV
(2012)Physics Letters BCombined results are reported from searches for the standard model Higgs boson in proton-proton collisions at s=7 TeV in five Higgs boson decay modes: γγ, bb, ττ, WW, and ZZ. The explored Higgs boson mass range is 110-600 GeV. The analysed data correspond to an integrated luminosity of 4.6-4.8 fb -1. The expected excluded mass range in the absence of the standard model Higgs boson is 118-543 GeV at 95% CL. The observed results exclude the ...Journal Article -
Search for heavy narrow dilepton resonances in pp collisions at √s=7 TeV and √s=8 TeV
(2013)Physics Letters BAn updated search for heavy narrow resonances decaying to muon or electron pairs using the CMS detector is presented. Data samples from pp collisions at s=7TeV and 8 TeV at the LHC, with integrated luminosities of up to 5.3 and 4.1fb−1, respectively, are combined. No evidence for a heavy narrow resonance is observed. The analysis of the combined data sets excludes, at 95% confidence level, a Sequential Standard Model ZSSM′ resonance lighter ...Journal Article -
Measurement of the differential dijet production cross section in proton–proton collisions at root s=7 TeV
(2011)Physics Letters BA measurement of the double-differential inclusive dijet production cross section in proton-proton collisions at √s=7 TeV is presented as a function of the dijet invariant mass and jet rapidity. The data correspond to an integrated luminosity of 36 pb-1, recorded with the CMS detector at the LHC. The measurement covers the dijet mass range 0.2 TeV to 3.5 TeV and jet rapidities up to |y|=2.5. It is found to be in good agreement with ...Journal Article -
Measurement of W+W- and ZZ production cross sections in pp collisions at sqrt(s) = 8 TeV
(2013)Physics Letters BThe W+W- and ZZ production cross sections are measured in proton-proton collisions at root s = 8 TeV with the CMS experiment at the LHC in data samples corresponding to an integrated luminosity of up to 5.3 fb(-1). The measurements are performed in the leptonic decay modes W+W- -> l'vl '' v and ZZ -> 2l2l', where l = e, mu and l'(l '') = e, mu, tau. The measured cross sections sigma (pp -> W+W-) =, 69.9 +/- 2.8 (stat.) +/- 5.6 (syst.) 3.1 ...Journal Article -
Measurement of the Lambda(b) cross section and the anti-Lambda(b) to Lambda(b) ratio with Lambda(b) to J/Psi Lambda decays in pp collisions at sqrt(s) = 7 TeV
(2012)Physics Letters BThe Λ b differential production cross section and the cross section ratio σ(Λ-b)/σ(Λb) are measured as functions of transverse momentum pTΛb and rapidity |y Λb| in pp collisions at s=7 TeV using data collected by the CMS experiment at the LHC. The measurements are based on Λ b decays reconstructed in the exclusive final state J/ψΛ, with the subsequent decays J/ψ→μ +μ - and Λ→pπ, using a data sample corresponding to an integrated luminosity ...Journal Article -
Measurement of the Υ (1S), Υ (2S), and Υ (3S) cross sections in pp collisions at √s=7TeV
(2013)Physics Letters BThe Υ(1S), Υ(2S), and Υ(3S) production cross sections are measured using a data sample corresponding to an integrated luminosity of 35.8±1.4pb-1 of proton-proton collisions at s=7TeV, collected with the CMS detector at the LHC. The Υ resonances are identified through their decays to dimuons. Integrated over the Υ transverse momentum range pTΥ<50GeV/c and rapidity range |yΥ|<2.4, and assuming unpolarized Υ production, the products of the ...Journal Article -
Search for a Higgs boson decaying into a Z and a photon in pp collisions at √s=7 and 8TeV
(2013)Physics Letters BA search for a Higgs boson decaying into a Z boson and a photon is described. The analysis is performed using proton-proton collision datasets recorded by the CMS detector at the LHC. Events were collected at center-of-mass energies of 7 TeV and 8 TeV, corresponding to integrated luminosities of 5.0fb-1 and 19.6fb-1, respectively. The selected events are required to have opposite-sign electron or muon pairs. No excess above standard model ...Journal Article -
Event shapes and azimuthal correlations in Z plus jets events in pp collisions at root s=7 TeV
(2013)Physics Letters BMeasurements of event shapes and azimuthal correlations are presented for events where a Z boson is produced in association with jets in proton-proton collisions. The data collected with the CMS detector at the CERN LHC at root s = 7 TeV correspond to an integrated luminosity of 5.0 fb(-1). The analysis provides a test of predictions from perturbative QCD for a process that represents a substantial background to many physics channels. ...Journal Article -
Search for heavy lepton partners of neutrinos in proton–proton collisions in the context of the type III seesaw mechanism
(2012)Physics Letters BA search is presented in proton-proton collisions at s=7TeV for fermionic triplet states expected in type III seesaw models. The search is performed using final states with three isolated charged leptons and an imbalance in transverse momentum. The data, collected with the CMS detector at the LHC, correspond to an integrated luminosity of 4.9fb -1. No excess of events is observed above the background predicted by the standard model, and ...Journal Article
