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 electron), ...
Measurement of the tt¯ production cross section in pp collisions at √s=8 TeV in dilepton final states containing one τ lepton
The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying τ lepton from the process tt¯→(ℓνℓ)(τντ)bb¯, where ℓ=e,μℓ=e,μ. The data sample corresponds ...
Inclusive and differential measurements of the tt¯ charge asymmetry in proton–proton collisions at √s=7 TeV
The tt¯ charge asymmetry is measured in events containing a charged lepton (electron or muon) and at least four jets, one of which is identified as originating from b-quark hadronization. The analyzed dataset corresponds ...
Measurement of the tt¯ production cross section in pp collisions at √s=7 TeV with lepton + jets final states
A measurement of the tt¯ production cross section in pp collisions at √s=7 TeV is presented. The results are based on data corresponding to an integrated luminosity of 2.3 fb−1 collected by the CMS detector at the LHC. ...
Measurement of the charge asymmetry in top-quark pair production in proton–proton collisions at √s=7 TeV
The difference in angular distributions between top quarks and antiquarks, commonly referred to as the charge asymmetry, is measured in pp collisions at the LHC with the CMS experiment. The data sample corresponds to an ...
