We present the recent measurement of the ttbar charge asymmetry in a dataset corresponding to an integrated luminosity of 4.7/fb, collected with the CMS detector at the LHC. In addition to the inclusive measurement, for the first time at the LHC also differential measurements are performed.

We present a measurement of the single top t-channel inclusive cross section in proton-proton collisions at sqrt(s) = 7 TeV with the CMS detector at LHC considering decay channels with a muon or an electron in the final state, using data samples corresponding to an integrated luminosity of 1.14/1.51 inverse fb for the muon/electron channel. After a selection optimized for the t-channel,...

We present a measurement of the top quark mass mtop in the dilepton decay channel tt ̄ → (l+νlb) (l−ν ̄lb ̄) in pp collisions at sqrt{s}=7 TeV. The data sample of the measurement corresponds to an integrated luminosity of 2.3 fb−1 collected with the CMS detector at the LHC. Events are selected by requiring two leptons, at least two jets and missing transverse energy. The mass is reconstructed...

Jet flavour tagging is one of the key ingredients of the diverse physics program of the CMS experiment.
Various flavour-taggers based on the lifetime and semileptonic decay of the heavy quarks have been implemented. They use jets, tracks, leptons and/or vertices. We exploit the \ttbar samples collected
at $\sqrt {s}=7$ TeV running of the LHC during the first half of 2011, to extract the...
