Study of χcJ (J = 0,1,2) decays to light meson pairs based on SU(3) flavor symmetry/breaking analysis*

Year: 2025

Type: article

Abstract: Based on available experimental results on decays, we investigated the , , , and decays using the SU(3) flavor symmetry/breaking approach, where P, V, and T denote light pseudoscalar, vector, and tensor mesons, respectively. With the decay amplitude relations determined by SU(3) flavor symmetry/breaking, we present the branching ratios for all and modes, including those without experimental data. While theoretical considerations strongly suppress or even forbid most and decays, we also provide quantitative predictions constrained by existing experimental data. Our results are expected to be accessible in future experiments at BESIII and the planned Super Tau-Charm Facility.
