摘要
A calculation of the hadronic matrix elements for K\to\pi\pi including \pi-\pi rescattering effects in a dispersion integral is presented. I study the dependence of the results on the matching scale \mu and use them to calculate the CP-parameter (\epsilon\prime/\epsilon). I find improved stability on the matching scale and good agreement with the experimental results.
