The role of final state interactions in epsilon'/epsilon

Abstract

The Standard Model prediction for epsilon'/epsilon is updated, taking into account the chiral loop corrections induced by final state interactions. The resulting value, epsilon'/epsilon = (17\pm 6)\times 10^{-4}, is in good agreement with present measurements.
