Abstract

A simple analysis of time-dependent B_s→ K⁺K^- transitions, based on recent results from the LHCb experiment, is presented. The benefits of adopting a fully consistent theoretical description of the B⁰_s-- B⁰_s mixing are stressed. It is shown that bounds on CPT violation in the B⁰_s-- B⁰_s system can be consistently obtained and that direct CP violation in B_s→ K⁺K^- can be robustly established, even in the presence of CPT violation in the mixing.
