Description
In this presentation i will first talk about the recent QCD LCSRs calculation of $D_s^\ast \to \phi$ helicity form factors and discuss the experiment potential of discovering exclusive $D_s^\ast$ weak decays, then i will discuss the width effect in the $D_s \to f_0 (\to \pi^+\pi^-) l\nu$ decay.
