Evidence of Non-Zero Mass Features for the Neutrinos Emitted at   Supernova LMC-'87A
  The observation of the neutrinos arrived from Supernova LMC-'87A shows, with a good confidence level, the existence of two massive neutrinos. For the unobserved third neutrino mass, could speculate two possibilities either that this mass is close to one of the two observed values or that this kind of neutrino has a negligible electronic flavor component.
