摘要：

Nonleptonic, electromagnetic decays of K‐mesons and K°–K̄° transition are treated with the effective Hamiltonians with ΔS = 1, 2. Matrix elements of four‐quark operators are calculated in the framework of Quark Confinement Model. The account of the intermediate scalar mesons turns out to allow to explain ΔI = 1/2 rule. The account of intermediate scalar and pseudo‐scalar states leads to experimental value of mass difference of KL°–KS° mesons. The obtained values for nonleptonic and electromagnetic decay widths as well as mass difference ΔmLS are in good agreement with experimental data. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA
