We study a general approach by analyzing constraints on the mass difference between the top and anti-top quarks. We present current bounds from Tevatron data, and comment on the prospects for improving these bounds at the LHC and the ILC.engjournal articlehttp://dx.doi.org/10.1007/s10751-013-0810-0https://link.springer.com/open access53Quark massT(T)over-bar productionRelativityEventsDecayConservationViolationTevatronColliderFermilab.Física-Modelos matemáticos
