Abstract

We discuss new, theoretically clean strategies to determine the angle γ of the unitarity triangle from B _d → DK _S(L), B _s → D η ^(′), D φ, ... decays, and point out that B _s → DK _S(L) and B _d → D π ⁰, D ρ ⁰, ... modes allow very interesting determinations of the B ⁰ _q – mixing phases φ _s and φ _d , respectively. Their colour-allowed counterparts and also offer new methods to probe γ.
