Azimuthal Angle Distribution in $B\to K^{\ast }(\to K\pi ){\ell }^{+}{\ell }^{-}$ at low invariant $m_{{\ell }^{+}{\ell }^{-}}$ Region

C. S. Kim, Yeong Gyun Kim, Cai-Dian Lu +1

We present the angular distribution of the rare B decay, $B\to K^{\ast }(\to K\pi ){\ell }^{+}{\ell }^{-}$. By studying the azimuthal angle distribution in the low invariant mass region of dilep…
