A Comprehensive Analysis of $B_s\to D_s^{\ast \ast }\ell {\nu }_{\ell }$ Decays Within and Beyond the Standard Model

Karthik Jain, Tarun Kumar, Barilang Mawlong +1

We examine the exclusive semileptonic decays $B_s\to D_s^{\ast \ast }\ell {\nu }_{\ell }$, with $D_s^{\ast \ast }=$ $\{D_{s0}^{\ast },D_{s1}^{\ast },D_{s1},D_{s2}^{\ast }\}$, within the Standard Model and beyo…
