Measurement of the charge asymmetry in top quark pair production in pp collisions (CMS)

We report on results of ttbar charge asymmetry measurements in the electron+jets and muon+jets channels, based on a dataset corresponding to an integrated luminosity of 5/fb. The data have been collected with the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC) at CERN at a ce...

description We report on results of ttbar charge asymmetry measurements in the electron+jets and muon+jets channels, based on a dataset corresponding to an integrated luminosity of 5/fb. The data have been collected with the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC) at CERN at a centre-of-mass energy of 7 TeV. An inclusive measurement of the ttbar charge asymmetry and three differential measurements as a function of the invariant mass, the transverse momentum, and the rapidity of the ttbar system are presented. All measurements are in agreement with the predictions of the standard model.
