O(m_d-m_u) Effects in CP-even and CP-odd K-->pi pi Decays

High Energy Physics - Phenomenology 2011-02-01 v1

Abstract

Strong isospin-breaking (IB) effects in CP-even and CP-odd K-->pi pi decays are computed to next-to-leading order (NLO) in the chiral expansion. The impact of these corrections on the magnitude of the Delta I=1/2 Rule and on the size of the IB correction, Omega_IB, to the gluonic penguin contribution to epsilon'/epsilon are discussed.
