- TL;DR Summary
- In beta decay an electron and neutrino are shot out of an atom. I was under the assumption that those particles decay from a w boson, but if that were the case, the atom would have to produce a lot of mass and then the mass would have to be converted into energy and carried away by the electron and neutrino. I am very confused.
During beta decay an electron and neutrino are emitted at very high speeds. I thought that the electron and neutrino were the product of w boson decay but I recently learned w bosons are over 80 GeV worth of energy. My question is, where does this mass come from? I know that atoms get enough excess energy from decay to create an electron and neutrino but how could they have enough energy to create a w boson? And this only gets worse with w+ decay
