Radiative semileptonic kaon decays
(1993) In Nuclear Physics, Section B 396(1). p.81-118- Abstract
We evaluate the matrix elements for the radiative kaon decays K+ → l+νlγ, l+νll′+l′- and K → πlνlγ (l, l′ = e, μ) to next-to-leading order in chiral perturbation theory. We calculate total rates and rates with several kinematical cuts and confront the results with existing data. Measurements at future kaon facilities will allow for a more detailed comparison between theory and experiment.
