The Decays K_L -> l^+ l^- l'^+ l'^- Revisited

Abstract

The double lepton pair decay modes of the K_L meson are analyzed including all contributions of order p^6 in Chiral Perturbation Theory. The experimentally established e^+ e^- e^+ e^- mode and the recently observed e^+ e^- mu^+ mu^- mode are discussed in detail.
