Direct CP violation in a variety of B decays

We give a brief review of direct CP violation effects in charmless B decays, both at the inclusive and at the exclusive level. It is emphasized that typical exclusive final states are composed of 2-4 K or π's, hence particle identification (in terms of K/π separation) is of crucial importance for studying CP violation in these modes. Another kind of ''charmless'' final state is also emphasized: b→dcc. The decay rate is tree dominant, while ''q2'' is necessarily above cc threshold hence in the domain of perturbative QCD. The CP asymmetry is therefore relatively clean and reliable. Theoretically, a few x107 B's would suffice if one could accumulate modes like B+→D+(*)D0(*). ((orig.))
