Radiative decays: a new flavour filter

Abstract

Radiative decays of the $1^3{D}_1$ orbital excitations of the $\rho$, $\omega$ and $\varphi$ to the scalars $f_0(1370)$, $f_0(1500)$ and $f_0(1710)$ are shown to provide a flavour filter, clarifying the extent of glueball mixing in the scalar states. A complementary approach to the latter is provided by the radiative decays of the scalar mesons to the ground-state vectors $\rho$, $\omega$ and $\varphi$. Discrimination among different mixing scenarios is strong.
