   <dc:title>CPT analysis with top physics</dc:title>
   <dc:creator>Ruiz Cembranos, José Alberto</dc:creator>
   <dcterms:abstract>We discuss the possibility of observing CPT violation from top antitop production in hadronic colliders. 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.</dcterms:abstract>
