Radiative Corrections to Double Dalitz Decays: Effects on Invariant Mass Distributions and Angular Correlations

High Energy Physics - Phenomenology 2009-11-07 v2

Abstract

We review the theory of meson decays to two lepton pairs, including the cases of identical as well as non-identical leptons, as well as CP-conserving and CP-violating couplings. A complete lowest-order calculation of QED radiative corrections to these decays is discussed, and comparisons of predicted rates and kinematic distributions between tree-level and one-loop-corrected calculations are presented for both pi-zero and K-zero decays.
