Abstract

A variety of CP violating asymmetries in B0B^0 decays is predicted in the Standard Model in terms of CKM (Cabibbo-Kobayashi-Maskawa) complex phases. These phases can also be determined from rate measurements of certain B+B^+ and BB^- decays. We focus on the following processes: B0ψKS, π+π, π0π0, ρ±π, BsDs+K, π0η, B+D0(\Dbar)K+, π+π0, π0K+, π+K0, ηK+B^0\to\psi K_S,~\pi^+\pi^-,~\pi^0\pi^0, ~\rho^{\pm}\pi^{\mp},~B_s\to D^+_s K^-,~\pi^0\eta, ~B^+\to D^0(\Dbar)K^+,~\pi^+\pi^0,~\pi^0 K^+,~ \pi^+ K^0,~\eta K^+ and their charge-conjugates. Complications due to gluonic-penguin and electroweak-penguin amplitudes are dealt with and are resolved. The importance of final state interaction phases in charged BB decay asymmetries is demonstrated in B+χc0π+,  χc0π+πB^+\to\chi_{c0}\pi^+,~~\chi_{c0}\to\pi^+\pi^- through the effect of the χc0\chi_{c0} width.
