Description
The calculations of isotopic amplitudes and their results for the direct CP-violating charge asymmetry in K± → 3π decays within the nonlinear and linear (σ-model) chiral Lagrangian approach are compared with each other. It is shown, that the latter, taking into account intermediate scalar resonances, does not reproduce the p4-corrections of the nonlinear approach introduced by Gasser and Leutwyler, being saturated mainly by vector resonance exchange. The resulting differences concerning the CP violation effect are traced in some detail. (author). 31 refs., 1 tab
