Description
We consider the nonleptonic and semileptonic decays of $D_s$-mesons into $ϕ$ and $f_0(980)$ mesons. QCD sum rules are used to calculate the form factors associated with these decays, and the correspondig decay rates. On the basis of data on $D_s^+\toπ^+π^+π^-$, which goes dominantly via the transition $D_s^+\to π^+f_0(980)$, we conclude that there is space for a sizeable light quark component on $f_0(980)$.
