Higher order QED corrections to muon decay spectrum
Abstract
Radiative corrections to polarized muon decay spectrum of the second and higher orders in alphaQED are considered. Leading and next-to-leading logarithmic approximations are used. Exponentiation of soft photons is discussed. The present theoretical uncertainty of the spectrum description is estimated.
