Decay $B\to K^{\ast }(\to K\pi ){\ell }^{+}{\ell }^{-}$ in covariant quark model

Stanislav Dubnička, Anna Z. Dubničková, Nurgul Habyl +3

Our article is devoted to the study of the rare $B\to K^{\ast }{\ell }^{+}{\ell }^{-}$~decay where $\ell =e,\mu ,\tau$. We compute the relevant form factors in the framework of the covariant quark mo…
