epsilon'/epsilon in the Standard Model

Abstract

In order to provide an estimate of eps'/eps several effective theories and physical effects have to be disentangled. In this talk I discuss how it is possible to predict eps '/eps taking into account all sources of large logs. The numerical result one obtains, ${\text{eps}}^{\prime }/\text{eps}\sim (1.7\pm 0.6)\cdot 10^{-4}$, is in good agreement with present measurements.
