New Parameterization in Muon Decay and the Type of Emitted Neutrino

Masaru Doi, Tsuneyuki Kotani, Hiroyuki Nishiura

Normal muon decay, ${\mu }^{+}\to e^{+}{\nu }_e\overline{{\nu }_{\mu }}$, is studied as a tool to discriminate between the Dirac and Majorana types of neutrinos and to survey the structure of the weak i…
