Description
The problem of a correct description of the partial width of the decay K+→π+π-e+ve in the quark model of superconductivity type is discussed. It is shown how to obtain the correct value of this partial width if one accounts for the contribution of the contact quark diagrams. These diagrams cannot be obtained by the current-algebra and the effective chiral lagrangians methods in the tree approximation. (orig.)
