Study of hadronic event-shape variables in multijet final states in pp collisions at √s = 7TeV
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 ...
Measurement of higher-order harmonic azimuthal anisotropy in PbPb collisions at s NN =2.76 TeV
Measurements are presented by the CMS Collaboration at the Large Hadron Collider (LHC) of the higher-order harmonic coefficients that describe the azimuthal anisotropy of charged particles emitted in sNN=2.76 TeV PbPb ...
Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s = 8 TeV
A search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at √s = 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 fb ...
Measurements of the tt̄ charge asymmetry using the dilepton decay channel in pp collisions at √s = 7 TeV
The tt̄ charge asymmetry in proton-proton collisions at √s = 7 TeV is measured using the dilepton decay channel (ee, eμ, or μμ). The data correspond to a total integrated luminosity of 5.0 fb−1, collected by the CMS ...
Measurement of the production cross section for a W boson and two b jets in pp collisions at √s=7 TeV
The production cross section for a W boson and two b jets is measured using proton–proton collisions at √s = 7 TeV in a data sample collected with the CMS experiment at the LHC corresponding to an integrated luminosity ...
