| contents | We investigate the strong decay $J/ψ\toρ^+ρ^-ω$ and the radiative decay $J/ψ\toγρ^0ω$, taking into account the $S$-wave $K^*\bar{K}^*$, $ρω$ and $ρϕ$ final-state interactions that dynamically generate the scalar meson $a_0(1710)$. Our results demonstrate that a clear peak structure emerges around 1.8~GeV in the $ρ^+ω$~($ρ^-ω$) invariant mass distribution of the strong decay, which can be associated with the $a_0(1710)$ resonance. Similarly, a distinct peak is predicted in the $ρ^0ω$ invariant mass distribution of the radiative decay. Our results show that clear peaks for the $a_0(1710)$ production should be observed in future experimental measurements of these processes by the BESIII and Belle II Collaborations, as well as the planned Super Tau-Charm Facility (STCF), helping to get more precise values of mass and width than presently available. |
