Resonant Scattering of Antineutrinos
The hypothesis of an unstable charged boson to mediate muon decay radically affects the cross section for the process $\overline{\ensuremath{\nu}}+e\ensuremath{\rightarrow}\overline{\ensuremath{\nu}}+{\ensuremath{\mu}}^{\ensuremath{-}}$ near the energy at which the intermediary may be produced. If the boson is assumed to have $K$-meson mass, the resonance occurs at an incident antineutrino energy of \ensuremath{\sim}2\ifmmode\times\else\texttimes\fi{}${10}^{12}$ ev. The flux of energetic antineutrinos produced in association with cosmic-ray muons will then produce two muon counts per day per square meter of detector, independently of the depth and the orientation at which the experiment is performed.
