The ∆I = 1/2 rule and direct CP violation ε/ε in kaon decays are studied within the framework of the effective Hamiltonian approach in conjunction with generalized factorization for hadronic matrix elements. We identify two principal sources responsible for the enhancement of ReA0/ReA2: the vertex-type as well as penguin-type corrections to the matrix… CONTINUE READING
