Form factors and branching fraction calculations for $B_s\to D_s^{(\ast )}{\ell }^{+}{\nu }_{\ell }$ in view of LHCb observation

Nakul R. Soni, Aidos Issadykov, Akshay N. Gadaria +3

In light of the LHCb observations about the $B_s\to D_s^{(\ast )}\ell {\nu }_{\ell }$ semileptonic decays, we study these channels within the Standard Model framework of covariant confined qu…
