Charmless nonleptonic rare decays ofBmesons

Abstract

Branching ratios of nonleptonic exclusive two-body decays of $B$ mesons without final-state charm particles are studied in detail. The technique used for evaluating the nonleptonic decay amplitudes is elucidated. The dominant charmless decay channels are $B_u^{+}\to K^{+}{\eta }^{\prime }, {\pi }^{+}{\eta }^{\prime }, {\rho }^{+}{\pi }^0, {\rho }^{+}\eta , {\rho }^{+}{\eta }^{\prime }, {\rho }^{+}\omega$, $B_d^0\to K^0{\eta }^{\prime }, \eta {\eta }^{\prime }, {\eta }^{\prime }{\eta }^{\prime }, K^{*+}{\pi }^{-}, {\rho }^{+}{\pi }^{-}, K^{*+}{\rho }^{-}, {\rho }^{+}{\rho }^{-}$, which should be interesting for experimental observation. The implications of the quark-diagram scheme are also discussed.
