Abstract

We describe how the angular analysis of vector-vector final states in B decays provides theoretically clean techniques for determination of CP violating phases. The quantity sin² (2β+ γ) can be cleanly obtained from the time dependent study of decays such as B_d(t)->D^*± ρ^∓, D^*± a₁^∓ etc. Similarly, one can use B_s(t)-> D_s^*± K^*∓ to extract sin² γ. A time independent study of the charged decay mode B^±-> D^*0( D^*0) K^*± can also be used to extract gamma.
