ChPT Progress on Non-Leptonic and Radiative Kaon Decays

Abstract

I discuss recent developments on non-leptonic and radiative kaon decays mainly related to direct CP-violation within the combined ChPT and 1/N_c expansion approaches. In particular, I review the status of K -> pi pi, epsilon_K', direct CP-violating K+ -> 3 pi Dalitz plot slope g and decay rate asymmetries, and the Standard Model prediction for Br(K_L -> pi0 e+ e-).Comment: 14 pages, 1 figure. Invited talk at KAON 07 International Conference, May 21-25 2007, Frascati, Italy. v2: Discussion in Section 3 somewhat enlarged and added references. Matches published verio
