Abstract |
We investigate the strong decay J=psi-* rho+rho-omega and the radiative decay J=psi-* gamma rho 0 omega, taking into account the S-wave K*K & strns;*, rho omega and rho phi final-state interactions, which dynamically generate the scalar meson a0(1710). Our results demonstrate that a clear peak structure emerges around 1.8 GeV in the rho+omega (rho-omega) invariant mass distribution of the strong decay, which can be associated with the a0(1710) resonance. Similarly, a distinct peak is predicted in the rho 0 omega invariant mass distribution of the radiative decay. Our results indicate that clear signals of a0(1710) production could be observed in future measurements of these processes at BESIII, Belle II, and the planned Super Tau-Charm Facility, thereby helping to determine its mass and width more precisely. |
