內容簡介：
The SU(3) flavor symmetry approach is independent of the detailed dynamics offering us an opportunity to relate different decay modes. Nevertheless, it cannot determine the sizes of the amplitudes by itself. However, if experimental data are enough, one may use the data to extract the amplitudes, which can be viewed as predictions based on symmetry. In view of some measured hadron decays, we study the
semi-leptonic weak decays of baryons,
,
semileptonic/two-body nonleptonic decays of hyperons, and
four-body semileptonic charm weak decays with the SU(3) flavor symmetry. Using the SU(3) flavor symmetry, we first obtain the amplitude relations among different decay modes, and then predict the relevant not-yet measured hadron decays. According to our predictions, some observables are accessible to the experiments at BESIII, LHCb and Belle-II.
