$B_s\to f_0(980)$ decays: Results from light-cone QCD Sum Rules

Abstract

We describe a light-cone QCD sum rule calculation of the $B_s\to f_0(980)$ transition form factors useful to predict the branching ratios of the rare decays $B_s\to f_0{\ell }^{+}{\ell }^{-}$, $B_s\to f_0\nu \bar{\nu }$ and of $B_s\to J/\psi f_0$ decay assuming factorization. We compare this channel to $B_s\to J/\psi \varphi$ as far as the possibility to determine the $B_s$ mixing phase is concerned.
