CPviolation in rareBdecays

$\mathrm{CP}$ violation in nonleptonic exclusive two-body decays of $B$ mesons without final-state charm particles are studied. For charged $B$ mesons, we consider those rare decay modes which have effectively only one single isospin component so that the final-state-interaction phase is dynamically generated from the timelike penguin diagrams that can be more reliably calculated. Various mechanisms responsible for the $\mathrm{CP}$-violating asymmetry in the neutral $B$ decay are elaborated.
