Description
A measurement of the mass difference between the top quark and the antitop quark (∆mt = mt − mt ) is performed using events with a muon and at least four jets in the muon+jets final state. Data collected in 2011 with the CMS detector at the LHC and corresponding to an integrated luminosity of 1.09 fb−1 are analyzed. The measured value of ∆mt = −1.2 ± 1.2 (stat.) ± 0.5 (syst.) GeV is consistent with the standard model.
