Search for quark compositeness in dijet angular distributions from pp collisions at √s=7 TeV
(Springer, 2015)
A search for quark compositeness using dijet angular distributions from pp collisions at √s=7 TeV is presented. The search has been carried out using a data sample corresponding to an integrated luminosity of 2.2 fb−1, recorded by the CMS experiment at the LHC. Normalized dijet angular distributions have been measured for dijet invariant masses from ...
Search for heavy quarks decaying into a top quark and a W or Z boson using lepton + jets events in pp collisions at √s=7 TeV
(Springer, 2013)
Results are presented from a search for the pair-production of heavy quarks, QQ¯¯¯¯, that decay exclusively into a top quark and a W or Z boson. The search is performed using a sample of proton-proton collisions at √s=7 TeV corresponding to an integrated luminosity of 5.0 fb−1, collected by the Compact Muon Solenoid experiment. The signal region is ...
Searches for supersymmetry using the M T2 variable in hadronic events produced in pp collisions at 8 TeV
(Springer, 2015)
Searches for supersymmetry (SUSY) are performed using a sample of hadronic events produced in 8 TeV pp collisions at the CERN LHC. The searches are based on the M T2 variable, which is a measure of the transverse momentum imbalance in an event. The data were collected with the CMS detector and correspond to an integrated luminosity of 19.5 fb−1. Two ...
Study of hadronic event-shape variables in multijet final states in pp collisions at √s=7 TeV
(Springer, 2014)
Event-shape variables, which are sensitive to perturbative and nonperturbative aspects of quantum chromodynamic (QCD) interactions, are studied in multijet events recorded in proton-proton collisions at √s=7 TeV. Events are selected with at least one jet with transverse momentum p T > 110 GeV and pseudorapidity |η| < 2.4, in a data sample corresponding ...
Measurement of Inclusive W and Z Boson Production Cross Sections in pp Collisions at √s=8 TeV
(American Physical Society, 2014)
A measurement of total and fiducial inclusive W and Z boson production cross sections in pp collisions at s√=8 TeV is presented. Electron and muon final states are analyzed in a data sample collected with the CMS detector corresponding to an integrated luminosity of 18.2±0.5 pb−1. The measured total inclusive cross sections times branching fractions ...
Measurement of associated W + charm production in pp collisions at √s = 7 TeV
(Springer, 2014)
Measurements are presented of the associated production of a W boson and a charm-quark jet (W + c) in pp collisions at a center-of-mass energy of 7 TeV. The analysis is conducted with a data sample corresponding to a total integrated luminosity of 5 fb−1, collected by the CMS detector at the LHC. W boson candidates are identified by their decay into ...
Combined Measurement of the Higgs Boson Mass in pp Collisions at √s=7 and 8 TeV with the ATLAS and CMS Experiments
(American Physical Society, 2015)
A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H→γγ and H→ZZ→4ℓ decay channels. The results are obtained from a simultaneous fit to the reconstructed invariant mass peaks in the two channels and for the two experiments. The measured masses from the individual ...
Long-range two-particle correlations of strange hadrons with charged particles in pPb and PbPb collisions at LHC energies
(Elsevier, 2015)
Measurements of two-particle angular correlations between an identified strange hadron (KS0 or Λ/Λ¯) and a charged particle, emitted in pPb collisions, are presented over a wide range in pseudorapidity and full azimuth. The data, corresponding to an integrated luminosity of approximately 35 nb−1, were collected at a nucleon–nucleon center-of-mass ...
Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s=7 eV
(Elsevier, 2015)
Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in ...
