Abstract
We present a measurement of the mass difference between t and t‾ quarks in lepton+jets final states of tt‾ events in 1fb-1 of data collected with the D0 detector from Fermilab Tevatron Collider pp‾ collisions at √ s=1.96TeV. The measured mass difference of 3.8± 3.7GeV is consistent with the equality of t and t‾ masses. This is the first direct measurement of a mass difference between a quark and its antiquark partner.
