Study of Form Factors and Observables in $B_c^{-}\to {\bar{D}}^{(\ast )0}{\ell }^{-}\bar{\hat{I}}{½}_{\ell }$ and $B_c^{-}\to D^{(\ast )-}{\ell }^{+}{\ell }^{-}$ decays

Utsab Dey, Soumitra Nandi

We investigate the decays $B_c^{-}\to {\bar{D}}^{(\ast )0}{\ell }^{-}\bar{\hat{I}}{½}_{\ell }$ and $B_c^{-}\to D^{(\ast )-}{\ell }^{+}{\ell }^{-}$ within the Standard Model (SM), employing perturbative…
