Asymmetries in $B\to K^{\ast }{\ell }^{+}{\ell }^{-}$ Decays and Two Higgs Doublet Model

Ishtiaq Ahmed, M. Jamil Aslam, M. Ali Paracha

The study of polarized branching ratio and different lepton polarization asymmeteries in the exclusive rare decays $B\to K^{\ast }{\ell }^{+}{\ell }^{-}$ ($\ell =\mu ,\tau$) have been m…
