Molecular components in the $J/\psi$ and the $\rho$-$\pi$ puzzle

Xing-Dao Guo, Dian-Yong Chen, Xue-Qian Li +2

Motivated by the large branching fractions of $J/\psi \to f_0(1710)\omega /f_0(1710)\varphi$ and the light exotic candidates, we find that there may exist molecular states composed of $f_0(1710…
