A large number of meson events have been recorded at the LHCb detector, especially some two-body hadronic decay modes. We analyzed the weak decays of the meson into two hadron states under the flavor SU(3) symmetry. The relations among amplitudes of into , , , and were investigated systematically, where P ( V) denotes a light pseudoscalar (vector) meson and denotes a light baryon. The mixing and mixing effects are also considered for the phenomenological discussions. We obtained the relations among decay widths of different decay channels. These results are helpful to study the two-body decay properties of the meson and test the flavor SU(3) symmetry.
