Rescattering Effects for (ε'/ε)
E. A. Paschos
Abstract
A calculation of the hadronic matrix elements for Kππincluding π-πrescattering effects in a dispersion integral is presented. I study the dependence of the results on the matching scale μand use them to calculate the CP-parameter (ε/ε). I find improved stability on the matching scale and good agreement with the experimental results.
