A neutrino (antineutrino)-induced four lepton event

We report observation of a neutrino (antineutrino)-induced event with two electrons, one positron, one positively charged muon, a neutral K meson, and seven gammas in an experiment performed in the FNAL 15-ft. bubble chamber with a 47% atomic mixture of neon in hydrogen. Estimated experimental elect...

Description
Summary:We report observation of a neutrino (antineutrino)-induced event with two electrons, one positron, one positively charged muon, a neutral K meson, and seven gammas in an experiment performed in the FNAL 15-ft. bubble chamber with a 47% atomic mixture of neon in hydrogen. Estimated experimental electron backgrounds are ∼10 −4 per track. At present we have no plausible interpretation of this event.
