Large Strong Phases and CP Violation in the Annihilation Processes ${\bar{B}}^0\to K^{+}{K}^{-}$, $K^{\ast \pm }{K}^{\mp }$, $K^{\ast +}{K}^{\ast -}$

Fang Su, Yue-Liang Wu, Ya-Dong Yang +1

The strong phases and CP violation in the rare ${\bar{B}}^0\to K^{+}{K}^{-}$, $K^{\ast \pm }{K}^{\mp }$, $K^{\ast +}{K}^{\ast -}$ decays are investigated. As these decays proceed only via annihilation type di…
