Abstract

Decay rates of

B^{0} (t) \to π^{+} π^{-}

B^{0} \to π^{-} K^{+}

B^{+} \to π^{+} K^{0}

(K_{S} \to π^{+} π^{-})

and of charge-conjugate processes are studied within flavor SU(3) symmetry and first-order SU(3) breaking. We show that these measurements can determine with a reasonable accuracy the two angles

α

and

γ

of the Cabibbo-Kobayashi-Maskawa unitarity triangle.
