μ-Meson Decay into Three Electrons

Abstract

The decay ${\mu }^{-}\to e^{-}+e^{-}+e^{+}$ via internal conversion is computed using a phenomenological matrix element for the $\mu e\gamma$ interaction. The result is compared with present experimental limits for this process and the results concerning the form factors in the matrix element are discussed. The energy distribution of the emitted electrons is also computed.
