Phenomenology of $B_s$ Decays

Abstract

Using the QCD sum rules technique we study several aspects of the phenomenology of the b-flavoured strange meson $B_s^0$. In particular, we evaluate the mass of the particle, the leptonic constant and the form factors of the decays $\overline{B_s^0}\to D_s^{+}{\ell }^{-}\bar{\nu }$, $\overline{B_s^0}\to D_s^{\ast +}{\ell }^{-}\bar{\nu }$, $\overline{B_s^0}\to K^{\ast +}{\ell }^{-}\bar{\nu }$. We also calculate, in the factorization approximation, a number of two-body non leptonic $\overline{B_s^0}$ decays.
