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.

Decay rho(0)->pi(+)+pi(-)+gamma and the coupling constant g(rho sigma gamma) Gokalp, A; Yılmaz, Osman (2000-11-01) The experimental branching ratio for the radiative decay rho (0)-pi (+) + pi (-) + gamma is used to estimate the coupling constant g(rho sigma gamma) for a set of values of sigma -meson parameters M-sigma and Gamma (sigma). Our results are quite different than the values of this constant used in the literature.
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.
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.
Magnetic moments of J(P)=3/2-baryons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (2014-12-29) The magnetic moments of the low lying, negative parity, spin-3/2 baryons, including the Lambda* baryon, are calculated within the light cone QCD sum rules method. The contributions coming from the positive parity, spin -3/2 baryons, as well as from the positive and negative parity spin -1/2 baryons are eliminated by constructing combinations of various invariant amplitudes corresponding to the coefficients of the different Lorentz structures. We also present the results for the magnetic moments of the posit...
Radiative Delta -> N gamma decay in light cone QCD Alıyev, Tahmasıb; Savcı, Mustafa (1999-12-01) The g(Delta N gamma) coupling for the Delta-->N gamma decay is calculated in the framework of the light cone QCD sum rules and is found to be g(Delta N gamma)=(1.6+/-0.2) GeV-1. Using this value of g(Delta N gamma) we estimate the branching ratio of the Delta(+)-->N gamma decay, which is in a very good agreement with the experimental result. [S0556-2821(99)02023-8].
