Radiative decays: A new flavor filter

Radiative decays of the 1(3)D(1) orbital excitations of the rho, omega and phi to the scalars f(0)(1370), f(0)(1500) and f(0)(1710) are shown to provide a flavor 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 phi. Discrimination among different mixing scenarios is strong.
