The coupling constants g_(rhoπγ) and g_(ωπγ) as derived from QCD sum rules}

We employ QCD sum rules to calculate the coupling constants g$_{\rho\pi\gamma}$ and g$_{\omega\pi\gamma}$ by studying the three point ${\rho\pi\gamma}$- and ${\omega\pi\gamma}$-correlation functions. Our results for the decay widths $\Gamma(\rho^0\to \pi^0\gamma)$ and $\Gamma(\omega\to \pi^0\gamma)$ calculated using the obtained coupling constants are in good agreement with the experimental values of these decay widths.
