so does the Higg field give the neutrino mass, and can neutrino velocity change?

so does the Higg field give the neutrino mass, and can neutrino velocity change? how close to c is neutrino velocity?

mathman

Neutrinos have mass. Therefore, they can vary in speed. It is hard to measure speed exactly, but they travel very close to c. Higgs field model presumably covers their mass as well as for anything else.

CarlB

According to the standard model, a neutrino can travel at any speed lower than c. Because their mass is so small, at normal energies they travel at very close to c.

Severian

In the Standard Model, the neutrino can gain a mass from the Higgs field just as the other particles do. However with just this, it is difficult to explain why their masses are so small. A better idea is to give them a Majorana mass term, which naturally leads to small nuetrino masses via the see-saw mechnism.

How does this apply to a photon? They have no mass (presumably unsullied by the Higgs) but have momentum.

Is this a "now you have it, now you don't, moment"?

Why the necropost? This looks like a prime example for a new thread.
