Abstract

We analyze the possibility of observing CPT violation in the top sector by looking for a mass difference between top and anti-top. We present current bounds on CPT violation in this sector from the Tevatron data, and analyze the prospects of improving these bounds at the LHC. We show that bounds at level of a percent can be obtained at future colliders.
