Description
In this study, we investigate the new physics effects in semileptonic decay $\bar{B}_s \to K^{*+}(\to K \pi) l^- \bar{\nu}_l$ which is induced by the $b \to u l\nu$ quark level transition. This decay process serves as an important probe for testing the Standard Model predictions and searching deviations that might indicate new physics. The new physics wilson coefficients are constrained by using the available experimental branching ratio meaurements of leptonic decay $B \to \mu \nu$ and semileptonic decays $B \to (\pi, \rho, \omega)l\nu$. We provide $q^2$-dependence of branching ratio, forward-backward asymmetry and longitudinal polarization of $K^*$ meson for the allowed new physics parameters.
