Prediction of various observables for $B_s^0\to D_s^{(\ast )-}{\ell }^{+}{\nu }_{\ell }$ within covariant confined quark model

In 2020, the LHCb collaboration reported the exclusive branching fractions for the channels $B_s^0\to D_s^{(\ast )-}{\mu }^{+}{\nu }_{\mu }$ for the very first time. In view of these observations, we…
