Footprints of New Physics in the angular distribution of $B_c\to D_s^{\ast }(\to D_s\gamma ,(D_s\pi )){\ell }^{+}{\ell }^{-}$ decays

Marwah Zaki, M. Ali Paracha, Faisal Munir Bhutta

We investigate the angular decay distribution of the four-fold $B_c\to D_s^{\ast }(\to D_s\gamma ){\mu }^{+}{\mu }^{-}$, and $B_c\to D_s^{\ast }(\to D_s\pi ){\mu }^{+}{\mu }^{-}$ decays that proceed…
