Modification of jet shapes in PbPb collisions at √sNN=2.76TeV
The first measurement of jet shapes, defined as the fractional transverse momentum radial distribution, for inclusive jets produced in heavy-ion collisions is presented. Data samples of PbPb and pp collisions, corresponding ...
Event activity dependence of Υ(nS) production in √SNN = 5.02 TeV pPb and √s = 2.76 TeV pp collisions
The production of Y (1S), Y (2S), and Y (3S) is investigated in pPb and pp collisions at centre-of-mass energies per nucleon pair of 5.02 TeV and 2.76 TeV, respectively. The datasets correspond to integrated luminosities ...
Search for baryon number violation in top-quark decays
A search for baryon number violation (BNV) in top-quark decays is performed using pp collisions produced by the LHC at √s = 8 TeV. The top-quark decay considered in this search results in one light lepton (muon or ...
Measurement of the triple-differential cross section for photon + jets production in proton-proton collisions at √s = 7 TeV
A measurement of the triple-differential cross section, d3σ/(dpγTdηγdηjet), in photon + jets final states using a data sample from proton-proton collisions at √s = 7 TeV is presented. This sample corresponds to an integrated ...
Search for new physics in events with same-sign dileptons and jets in pp collisions at √s = 8 TeV
A search for new physics is performed based on events with jets and a pair of isolated, same-sign leptons. The results are obtained using a sample of proton-proton collision data collected by the CMS experiment at a ...
Inclusive search for a vector-like T quark with charge 2/3 in pp collisions at √s=8 TeV
A search is performed for a massive new vector-like quark T, with charge 2 3 , that is pair produced together with its antiparticle in proton–proton collisions. The data were collected by the CMS experiment at the Large ...

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−1 ...
Studies of azimuthal dihadron correlations in ultra-central PbPb collisions at √sNN =2.76 TeV
Azimuthal dihadron correlations of charged particles have been measured in PbPb collisions at √sNN = 2.76TeV by the CMS collaboration, using data from the 2011 LHC heavy-ion run. The data set includes a sample of ultra-central ...
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 ...
