摘要：

It is known that the existing experimental limit for CPT violation is rather poor-the 10% level at best. For this reason, we study experimental tests for CPT violation in B decays. We show that BBBAR mixing as well as CP-violating asymmetries can reveal CPT violation. We also point out that, with possible CPT violation, further experimental study is necessary in order to obtain the value for DELTAm/GAMMA from the rate of same-sign dilepton events.
