| Abstract: | Based on the understanding of nonleptonic decays of charmed meson, the relative ratio Br(Ds+→f0(975)π+/Br(Ds+→фπ+) is calculated. We argue that only (ss) component of f0(975) contributes to it dominantly. The numerical result proves f0(975) to be almost a pure (ss) state if the newly measured resultant value of the decay is trustable, and the conclusion is very usefulinformation as a clue for clarifying up the puzzle of 0++ meson f0(975). |
