Abstract:
Using the method of tabing a μ first, then checking the recoil side to see if it is a Ds meson, two Ds→μv and three Ds→τv→μvvv candidate events are found from a data sample corresponding to 22.3ph-1, which has been collected at BES at Ecm=4.03GeV.The...

Abstract:
The flavor-changing raciative B decays and flavo-conserving radiative decays of groundstate mesons are studied with another screened potential model. The results are compared with the counterparts of the comell potential and El hassan's work.
