Abstract

We show that both the weak phase βand the strong phase δ_d can be determined from the time-dependent measurement of B_d -> D^*± D^∓ decays, whose final states are non-CP eigenstates. It is also possible to extract βfrom B_d -> D^*± D^*∓ transitions without doing the angular analysis. Possible final-state rescattering effects in B_d -> D^(*)± D^(*)∓ channels are discussed by means of the isospin analysis. We emphasize that it is worthwhile to check whether the naive factorization approximation works or not for such B-meson decay modes into two heavy charmed mesons.
