Chiral loop corrections and isospin violation effects in epsilon'/epsilon

AuthorsPich, Antonio
Issue Date2004
CitationNuclear Physics B Proceedings Supplements 133: 233-238 (2004)
AbstractA complete analysis of isospin breaking in K→2π amplitudes, including both strong and electromagnetic corrections at next-to-leading order in chiral perturbation theory, has been achieved recently. We discuss the implication of these effects, together with the previously known chiral loop corrections, on the direct CP-violating ratio epsilon'/epsilon.
