报告摘要:
Four-body semileptonic exclusive decays can receive contributions from the nonresonant and various resonant contributions. Therefore, these decays area good laboratory for probing the internal structure of light hadrons. Due to our poor understanding of hadronic interactions, the evaluations of the D->MM form factors are difficult and often plugged with large uncertainties.In the lack of reliable calculations, symmetries provide very important information for particle physics. Iin this talk, l will introduce the study of four body semileptonic D->PPlv and D->PVlv decays based on the SU(3) flavor analysis. l will firstly construct the hadronic amplitude relations between different decay modes, use the available data to extract the hadronic amplitudes, then predict the not-yet-measured modes for further tests in experiments, and finally analyze the contributions with the nonresonance the light scalar meson resonances, the vector meson resonances, the axial vector meson resonances, and the tensor meson resonances in the branching ratios.
