CP violation in charged kaons

A calculation is performed of the asymmetry A=GAMMA(K/sup +/..--> pi../sup +/..pi../sup +/..pi../sup -/)-GAMMA(K/sup -/..--> pi../sup -/..pi../sup -/..pi../sup +/)) /(GAMMA(K/sup +/..--> pi../sup +/..pi../sup +/..pi../sup -/)+GAMMA(K/sup -/..pi../sup -/..pi../sup -/..pi../sup +/)) in the Kobayashi-Maskawa model using soft-pion results of current algebra. The prediction obtained is =0.74Vertical Barepsilon'Vertical Bar, where epsilon' is the CP-violating parameter of neutral kaons involving violations of the ..delta..I=1/2 rule.
