On neutrinos.

How are the electron neutrino, the muon neutrino and the tau neutrino different from each other (except for the leptonic number they carry)?

I heard they BEHAVE like their associated Lepton (el., muon, tau). If so, in what way?

Thanks.

That would be VERY strange considering that the neutrinos have NO charge, while their "associated leptons" do.

Zz.

Although they are all very light, the different neutrinos have different masses.

They form an isospin doublet together with the associated lepton.
