Partial-decay-rate asymmetries of charged bottom mesons andCPviolation

The partial-decay-rate asymmetries of charged-bottom-meson decays ${B}_{u}^{\ifmmode\pm\else\textpm\fi{}}$,${B}_{c}^{\ifmmode\pm\else\textpm\fi{}}$\ensuremath{\rightarrow}PP and PV are systematically studied and estimated. More attention has been paid to penguin contributions. We find that ${B}_{c}^{\mathrm{\ensuremath{-}}}$\ensuremath{\rightarrow}${\ensuremath{\rho}}^{\mathrm{\ensuremath{-}}}$D${\ifmmode\bar\else\textasciimacron\fi{}}^{0}$,${K}^{0}$${F}^{\mathrm{\ensuremath{-}}}$ and ${\mathit{B}}_{\mathit{u}}^{\mathrm{\ensuremath{-}}}$\ensuremath{\rightarrow}${\mathit{F}}^{\mathrm{\ensuremath{-}}}$${\mathit{D}}^{0\mathrm{*}}$,${\mathit{F}}^{\mathrm{\ensuremath{-}}\mathrm{*}}$${\mathit{D}}^{0}$ are extremely promising because of their large asymmetry and small number of bb\ifmmode\bar\else\textasciimacron\fi{} pairs needed for testing them.
