Direct Measurement of the Mass Difference Between Top and Antitop Quarks
Abstract
We present a measurement of the mass difference between t and {bar t} quarks in lepton+jets final states of t{bar t} events in 1 fb{sup -1} of data collected with the D0 detector from Fermilab Tevatron Collider p{bar p} collisions at {radical}s = 1.96 TeV. The measured mass difference of 3.8 {+-} 3.7 GeV is consistent with the equality of t and {bar t} masses. This is the first direct measurement of a mass difference between a quark and its antiquark partner.
