Final State Interactions and eps'/eps

arXiv:hep-ph/0010011 · doi:10.1016/S0920-5632(01)01150-1

Abstract

I discuss the role of strong final state interactions (FSI) in K \to 2πdecays. In this case strong FSI effects can be resummed [1,2] by solving the Omnès problem for K\to 2πamplitudes. Implications for the CP conserving Delta I=1/2 ratio and the direct CP violation parameter eps'/eps are also discussed.
