Calculation of coupling constant g_phi-pi-gamma in QCD sum rules

Abstract

The coupling constant of g_phi-pi-gamma decay is calculated in the method of QCD sum rules. A comparison of our prediction on the coupling constant with the result obtained from analysis of the experimental data is performed.
