AbstractAbstract
[en] Using the chiral σ model with broken U(3)LxU(3)R symmetry we have calculated in the p4-approximation a difference between the slope parameters g+ and g- describing the energy distributions of ''odd' pions in K+→π+π+π- and K-→π-π-π+ decays. The result is: (g+ - g-)/(g+ + g-) = -(1.9±0.8)10-2s2s3 sin δ, where s2, s3 and δ are the parameters of the Kobayashi-Maskawa mixing matrix. (author). 28 refs, 3 figs
