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 -
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 -
Measurement of the hadronic activity in events with a Z and two jets and extraction of the cross section for the electroweak production of a Z with two jets in pp collisions at √s=7 TeV
(2013)Journal of High Energy PhysicsThe first measurement of the electroweak production cross section of a Z boson with two jets (Zjj) in pp collisions at s√=7 TeV is presented, based on a data sample recorded by the CMS experiment at the LHC with an integrated luminosity of 5 fb−1. The cross section is measured for the ℓℓjj (ℓ = e, μ) final state in the kinematic region m ℓℓ > 50 GeV, m jj > 120 GeV, transverse momenta pjT>25 GeV and pseudorapidity |η j| < 4.0. The ...Journal Article -

Searches for Higgs bosons in pp collisions at √s=7 and 8 TeV in the context of four-generation and fermiophobic models
(2013)Physics Letters BSearches are reported for Higgs bosons in the context of either the standard model extended to include a fourth generation of fermions (SM4) with masses of up to 600 GeV or fermiophobic models. For the former, results from three decay modes (ττ, WW, and ZZ) are combined, whilst for the latter the diphoton decay is exploited. The analysed proton-proton collision data correspond to integrated luminosities of up to 5.1 fb-1 at 7 TeV and up ...Journal Article -
Inclusive search for supersymmetry using razor variables in pp collisions at √s=7 TeV
(2013)Physical Review LettersAn inclusive search is presented for new heavy particle pairs produced in √s=7 TeV proton-proton collisions at the LHC using 4.7±0.1 fb−1 of integrated luminosity. The selected events are analyzed in the 2D razor space of MR, an event-by-event indicator of the heavy particle mass scale, and R, a dimensionless variable related to the missing transverse energy. The third-generation sector is probed using the event heavy-flavor content. ...Journal Article -
Search for physics beyond the standard model in events with τ leptons, jets, and large transverse momentum imbalance in pp collisions at √s =7 TeV
(2013)The European Physical Journal CA search for physics beyond the standard model is performed with events having one or more hadronically decaying τ leptons, highly energetic jets, and large transverse momentum imbalance. The data sample corresponds to an integrated luminosity of 4.98 fb−1 of proton-proton collisions at s√=7 TeV collected with the CMS detector at the LHC in 2011. The number of observed events is consistent with predictions for standard model processes. ...Journal Article -
Search for heavy resonances in the W/Z-tagged dijet mass spectrum in pp collisions at 7 TeV
(2013)Physics Letters BA search has been made for massive resonances decaying into a quark and a vector boson, qW or qZ, or a pair of vector bosons, WW, WZ, or ZZ, where each vector boson decays to hadronic final states. This search is based on a data sample corresponding to an integrated luminosity of 5.0 fb-1 of proton-proton collisions collected in the CMS experiment at the LHC in 2011 at a center-of-mass energy of 7 TeV. For sufficiently heavy resonances ...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 -
Measurement of the inelastic proton-proton cross section at root s=7 TeV
(2013)Physics Letters BA measurement is presented of the inelastic proton-proton cross section at a centre-of-mass energy of root s = 7 TeV. Using the CMS detector at the LHC, the inelastic cross section is measured through two independent methods based on information from (i) forward calorimetry (for pseudorapidity 3 <vertical bar eta vertical bar < 5) in collisions where at least one proton loses more than 5 x 10(-6) of its longitudinal momentum, and (ii) the ...Journal Article
