摘要：

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).
