κK*⁰γ-vertex in light cone QCD sum rules
(Amer Physical Soc, 2008) Gokalp, A.; Sarac, Y.; Yilmaz, O.; Physics Group; 06. School Of Engineering; 01. Atılım University
We investigate the kappa K*(0)gamma-vertex in the framework of light cone QCD sum rules. We estimate the coupling constant g(kappa K)*(0)gamma, and compare our result with that used in the nonlinear chiral Lagrangian approach using the vector-meson dominance model in the SU(3) limit.
Κk⁺π^{-< Vertex in Light Cone Qcd Sum Rules}
(Amer Physical Soc, 2010) Baytemir, G.; Sarac, Y.; Yilmaz, O.; Physics Group; 06. School Of Engineering; 01. Atılım University
In this work we study the kappa K+pi(-) vertex in the framework of light cone QCD sum rules. We predict the coupling constant g kappa K+pi(-) to be g kappa K+pi(-) = (6.0 +/- 1.0) GeV and estimate the scalar f(0) - sigma mixing angle from the experimental ratio g(2)(kappa -> K pi)/g(2)(sigma -> pi pi).
