Abstract

A measurement of the mass difference between the top quarks and the antitop quark (Delta m_t - m_tbar) is performed using events with a muon and multi-jets in the final state produced at the LHC in pp collisions at sqrt(s)=7 TeV. The date is collected in 2011 with the CMS detector and corresponds to an integrated luminosity of 1.09 fb-1. The value of Delta m_t = -1.2 +/- 1.2 (stat) +/- 0.5 (syst) GeV is obtained.
