Main Question or Discussion Point

I know there's a difference between how they're detected. (Cherenkov radiation cone size) They have different "flavors." (I'm not sure what that means.) There's a difference in their simbol. (Ve, Vu, Vt) And they have different masses. But that's all I know. There must be something more to the difference. My guess is it has something to do with how they interact using the weak force.

We don't know.

For each fermion doublet (up-quark,down-quark), (e,μ) and the corresponding (e-,μ-neutrino) there are two additonal doublets which are identical in all quantum numbers except flavor. We don't know why they are there, and why three.
