Available in PDF, EPUB and Kindle. Book excerpt: The authors calculate the rates and lepton (l) invariant mass distributions for decays of the form 0{sup -+} → ll−?, which are important radiative corrections to the purely leptonic decays 0{sup -+} → l+l−. The approach uses the loop diagrams which arise by including the two photon intermediate state and they retain the imaginary parts of the loops--a radiative extension of the unitarity bound for the process. These results are compared with those obtained using a model in which the meson couples directly to the leptons.
