Abstract

We consider massive Dirac electron antineutrino to be observed in the muon decay, μe+νˉe+νμ\mu^{-} \rightarrow e^- +\bar{\nu}_{e} + \nu_{\mu}, at rest in the LAB reference frame. A computation of νˉe\bar{\nu}_{e} differential direct spectral shape and angular distribution was performed. This has resulted in transverse component of the neutrino polarization emerging from the nonstandard S, T sector of the Lorentz structure in the Fermi leptonic charged weak interaction. The calculation is based on empirical values of the coupling parameters.
