These neutrino oscillation parameters are fundamental physical constants in the same way that the mass and charge of the electron are fundamental. Neutrino research, because of the scale, cost and ...

They don’t have an electric charge, have a small mass ... the interaction produces a muon-neutrino. The same goes for electrons (electron-neutrino) and tauons (tau-neutrino).

Since neutrinos don't carry a charge, scientists can only tell the two apart based on the fact an electron neutrino will pop into existence alongside a positron, while an electron antineutrino ...
