We employ QCD sum rules to calculate the coupling constants g(rhopigamma) and g(rhopigamma) by studying the three point rhopigamma and omegapigamma correlation functions. Our results are in good agreement with the coupling constants g(rhopigamma) and g(omegapigamma) that are deduced utilizing the experimentally measured values of the Gamma(rho(0) --> pi(0)gamma) and Gamma(omega --> pi(0)gamma) decay widths.

Coupling constants g(phi sigma gamma) and g(phi alpha o gamma) as derived from QCD sum rules
Gokalp, A; Yılmaz, Osman (2002-05-01)
We employ QCD sum rules and utilize omegaphi-mixing to calculate the coupling constants g(phisigmagamma) and g(phia0gamma) by studying the three point phisigmagamma- and phia(0)gamma-correlation functions. Our results are consistent with the previous estimations of these coupling constants in the literature.
The gK(0)(*)K pi coupling constant in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (2001-01-01)
The strong coupling constant g kappa (0)*kappa pi of the scalar K-0* meson decay to K pi is calculated in light cone QCD sum rule. The predicted value of the coupling constant g kappa (0)*kappa pi is in a good agreement with the experimental result.
The phi a(0)gamma- and phi sigma gamma-vertices in light cone QCD
Gokalp, A; Yılmaz, Osman (2002-01-24)
We study phia(0)gamma- and phisigmagamma-vertices in the framework of the light cone QCD sum rules and we estimate the coupling constants gphia(0)gamma and gphisigmagamma utilizing omega-phi mixing. We compare our results with the previous estimations of these coupling constants in the literature obtained from phenomenological considerations.
Coupling constants g alpha(0)omega gamma and g alpha(0)p gamma as derived from QCD sum rules
Gokalp, A; Yılmaz, Osman (2001-11-01)
We consider the two point correlation function of a scalar current in the QCD sum rule approach to estimate the overlap amplitude of the a(o)-meson. We then employ QCD sum rules to calculate the coupling constants g(omegaaogamma) and g(rhoaogamma) by studying the three point a(o)omegagamma- and a(o)rhogamma-correlation functions.
The radiative K* meson decays in QCD
Alıyev, Tahmasıb; Iltan, E (Springer Science and Business Media LLC, 1996-06-01)
The g(K0*K0 gamma) and g(K+*K+gamma) coupling constants and the radiative decay widths are calculated in the context of QCD sum rules. It is found that the discrepancy between the experimental data and theoretical results still exists.
