Determination of the $\eta$-${\eta }^{\prime }$ mixing angle

Abstract

We extract $\eta$-${\eta }^{\prime }$ mixing angle and the ratios of decay constants of light pseudoscalar mesons ${\pi }^0$, $\eta$ and ${\eta }^{\prime }$ using recently available BaBar measurements on $\eta$-photon and ${\eta }^{\prime }$-photon transition form factors and more accurate experimental data for the masses and two-photon decay widths of the light pseduoscalar mesons.
