Influence of CP violation on energy spectra in K± → π±π±π-+ decays

Description

Using the chiral σ-model with broken U(3)L x U(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)x10-2 s2s3 sin δ, where s2, s3 and δ are the parameters of the Kobayashi-Maskawa mixing matrix. (orig.)
