Abstract:
QED radiative corrections to polarized muon decay spectrum are considered. Leading and next--to--leading logarithmic approximations are used. Exponentiation of soft radiation is discussed. The present theoretical uncertainty of the spectrum description is estimated.- muon: leptonic decay
- muon: polarization
- muon: width
- differential cross section
- quantum electrodynamics: radiative correction
- perturbation theory: higher-order
- leading logarithm approximation: higher-order
- fragmentation function
- numerical calculations
