Abstract
We study Semileptonic $B_s$-meson decay ($B_s\rightarrow$ $K$ $l^+\nu_l$) using Covariant Confined Quark Model (CCQM) which has built-in infrared confinement. The transition form factors are calculated using CCQM in entire range of physical momentum transfer. They can be further utilized to compute the branching fractions of $B_s$ meson. Our preliminary results for form factors $f_+ (0)$ and $A_+(0)$ are 0.25 and 0.21, respectively, which are consistent with available QCD results.
