英文摘要	Scalar mesons a(0)(0)(980) and f(0)(980) can mix with each other through isospin violating effects, and the mixing intensity has been predicted at the percent level in various theoretical models. However the mixing has not been firmed established on the experimental side to date. In this work we explore the possibility to extract the a(0)-f(0) mixing intensity using weak decays of heavy mesons: D-s -> [pi(0), pi(+) pi(-)]e(+) v, B-s -> [pi(0) eta, pi(+) pi(-)]l(+)l(-) and the B-s -> J /Psi[pi(0) eta, pi+ pi(-)] decays. Based on the large amount of data accumulated by various experimental facilities including BEPC-II, LHC, Super KEKB and the future colliders, we find that the ao-fo mixing intensity might be determined to a high precision, which will lead to a better understanding of the nature of scalar mesons.
