Nonleptonic kaon decays and nonperturbative QCD effects in chiral-bag model

  • Published:

Abstract

The instanton induced-term, proposed by Konishi and Ranfone [1] was introduced in the chiral-bag model based analysis ofK→2π decays. Almost perfect fit of the experimental data was possible with the induced-term coefficient\(\tilde C_1 \cong 1,4\). However, this conclusion, which is appreciably larger than the rough theoretical estimate [1] (which was\(\tilde C_1 = 0.15\) m s /μ) depends on the approximation used in the theoretical approach.
