Hadronic Corrections at O(alpha^2) to the Energy Spectrum of Muon Decay

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/214778We consider the impact of O(alpha^2) hadronic corrections to the energy spectrum of the decay electron in muon decay. We find that the correction can be described, within good approximation, by a linear function in the electron energy. Explicit expressions for the form factors needed in an approach based on dispersion integrals are given.12 pages Latex with 4 figuresHigh Energy Physics - PhenomenologyHadronic Corrections at O(alpha^2) to the Energy Spectrum of Muon Decaytext
