Physics Beyond the Standard Model
... Where Does Mass Come From? The electroweak “gauge” theory only has conserved currents for its weak charges if the W’s and Z are massless, like the photon is. It also helps if quarks and leptons are massless in the Energy. To maintain this, but yet have physical masses, we fill the vacuum with som ...
