Search for the decays $J/\psi \to \gamma \rho \varphi$ and $J/\psi \to \gamma \rho \omega$

Abstract

Using 58 million $J/\psi$ events collected with the Beijing Spectrometer (BESII) at the Beijing Electron-Positron Collider, the decays $J/\psi \to \gamma \varphi \rho$ and $J/\psi \to \gamma \omega \rho$ are searched for, and upper limits on their branching fractions are reported at the 90% C. L. No clear structures are observed in the $\gamma \rho$, $\gamma \varphi$, or $\rho \varphi$ mass spectra for $J/\psi \to \gamma \varphi \rho$ nor in the $\gamma \rho$, $\gamma \omega$, or $\rho \omega$ mass spectra for $J/\psi \to \gamma \omega \rho$.
