Abstract In this paper we revisit $$D_s \rightarrow f_0(980)$$ D s → f 0 ( 980 ) form factors from the light-cone sum rules based on the $${\bar{q}}q$$ q ¯ q picture of $$f_0(980)$$ f 0 ( 980 ) . The main motivation of this study is the decay width of $$D_s^+ \rightarrow \left[ \pi \pi \right] _{S}^...
