Their presence is "very strong evidence" that a muon antineutrino can transform itself into an electron antineutrino through a hypothetical process that theorists call neutrino oscillation, says Fred J. These pions decay into muons, muon neutrinos, muon antineutrinos, and electron neutrinos, but not electron antineutrinos. |
