QCD sum rule analysis of the coupling constants g_{ρηγ} and g_{ωηγ}

C. Aydin, A. H. Yilmaz

The coupling constants g${}_{\rho \eta \gamma }$ and g${}_{\omega \eta \gamma }$ are calculated using QCD sum rules method by studying the three point $\rho \eta \gamma$ and $\omega \eta \gamma$ correlation functions. A comparison of the…
