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.

Coupling constant g (rho sigma gamma) as derived from QCD sum rules Gokalp, A; Yılmaz, Osman (2001-08-01) We employ QCD sum rules to calculate the coupling constant g(rho sigma gamma) by studying the three-point rho sigma gamma correlation function. Our result is consistent with the value of this coupling constant obtained using vector meson dominance of the electromagnetic current and the experimental rho (o) photoproduction data.
Tensor form factors of B -> K-1 transition from QCD light cone sum rules Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-05-30) The tensor form factors of B into p-wave axial vector meson transition are calculated within light cone QCD sum rules method. The parametrizations of the tensor form factors based on the series expansion are presented.
Fourth generation effects in rare exclusive B -> K*l(+)l(-) decay Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2000-10-02) Influence of the fourth generation, if ever exists, on the experimentally measurable quantities such as invariant dilepton mass distribution, lepton forward-backward asymmetry, and the ratio Gamma(L)/Gamma(T) of the decay widths when K* meson is longitudinally and transversally polarized, is studied. Using the experimental results on the branching ratios for the B --> X(s)gamma and semileptonic B --> X(c)l (v) over bar decays, the two possible solutions of the 4 x 4 Cabibbo-Kobayashi-Maskawa factor Vt'sVt'b...
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.
Vector meson dominance and radiative decays of heavy spin-3/2 baryons to heavy spin-1/2 baryons Alıyev, Tahmasıb; Savcı, Mustafa (2012-04-10) Using the calculated values of the strong coupling constants of the heavy sextet spin-3/2 baryons to sextet and antitriplet heavy spin-1/2 baryons with light vector mesons within the light cone QCD sum rules method, and vector meson dominance assumption, the radiative decay widths are calculated. These widths are compared with the "direct" radiative decay widths predicted in the framework of the light cone QCD sum rules.
