Abstract

We have calculated the first-order radiative corrections to the muon decay

μ^{+} \to e^{+} ν_{e} {\bar{ν}}_{μ}

along with the radiative decay

μ^{+} \to e^{+} ν_{e} {\bar{ν}}_{μ} γ

for the case of a single intermediate-mass Dirac neutrino mixing in the three-neutrino world. The method of dimensional regularization was used. The

e^{+}

spectra are shown for both unpolarized and polarized

μ^{+}

decays.
