英文摘要: Based on the understanding of nonleptonic decays of charmed meson, the relative ratio Br(D9s --> fo(975)pi+/Br(D9s --> phi-pi-+) is calculated. argue that only (ssBAR) component of fo(975) contributes to it dominantly. The numerical result proves fo(975) to be almost a pure (ssBAR) state if the newly measured resultant value of the decay is trustable, and the conclusion is very useful information as a clue for clarifying up the puzzle of 0++ meson fo(975).
