Two mixing angle description of radiative VPgamma decays

Abstract

An analysis of various radiative $VP\gamma$ decays is performed using the two mixing angle description of the $\eta$-${\eta }^{\prime }$ system. The agreement is excellent. Our results are expressed both in the ``octet-singlet'' and in the ``quark-flavour'' basis. It turns out that at the present experimental accuracy, the two angles are significantly different in the former, but not in the latter basis.
