Abstract
A D0 analysis measuring the charge asymmetry Ab_sl of like-sign dimuon events due to semileptonic b-hadron decays at the Fermilab Tevatron Collider has shown indications of possible anomalous CP violation in the mixing of neutral B mesons. This result has been used to extract the first senstivity to CPT violation in the B0_s system. A procedure to explore further this anomaly by specifically measuring the semileptonic charge asymmetry, as_sl, in B0_s decays is described, as well as how a variant of this analysis can be used to explore a larger set of CPT-violating parameters in the B0_s system for the first time.
