Abstract
It was recently pointed out that inclusive B⁰(t) decays could show mixing-induced CP violation. The totally inclusive asymmetry is expected to be tiny [ ${\cal O}(10^{-3})$ ] because of large cancellations among the asymmetries in the charmless, single charm and double charm final states. Enriching particular final state configurations could significantly increase the CP-asymmetry and observability. Such studies can extract fundamental CKM (Cabibbo-Kobayashi-Maskawa) parameters, and (perhaps) even $\Delta m(B_s)$ . A superb vertex detector could see CP violation with $10^5 \; (10^6)$ flavor-tagged $B_s \; (B_d)$ mesons within the CKM model. Because the effects could be significantly larger due to new physics, they should be searched for in existing or soon available data samples.
