Higher order QED corrections to muon decay spectrum

چکیده
Radiative corrections to polarized muon decay spectrum of the second and higher orders in αQED 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.

متن کاملSecond Order Corrections to the Muon Lifetime and the Semileptonic B Decay
In this article two-loop QED corrections to the muon decay and corrections of order αs to the semileptonic decay of the bottom quark are considered. We compute the imaginary part of the four-loop diagrams contributing to the corresponding fermion propagator in the limit of small external momentum. The on-shell condition is obtained with the help of a conformal mapping and Padé approximation. Vi...
متن کاملCorrections to the fluxes of a Neutrino Factory
In view of their physics goals, future neutrino factories from muon decay aim at an overall flux precision of O(1%) or better. We analytically study the QED radiative corrections to the neutrino differential distributions from muon decay. Kinematic uncertainties due to the divergence of the muon beam are considered as well. The resulting corrections to the neutrino flux turn out to be of order ...
متن کاملConsiderations Concerning the Radiative Corrections to Muon Decay in the Fermi and Standard Theories
The FAC, PMS, and BLM optimization methods are applied to the QED corrections to the muon lifetime in the Fermi V-A theory. The FAC and PMS scales are close to me, while the BLM scale nearly concides with the geometric average √ memμ. The optimized expressions are employed to estimate the third order coefficient in the α(mμ) expansion and the theoretical error of the perturbative series. Using ...
