It turns out that the Higgs Boson is really an allusive particle which is 125 times more massive than the protons. The actual calculations of the mass of the Higgs Bosson are quite complicated, but the principle is outlined in the video above, where Dr. Don Lincoln , from Fermilab, explains how it is that the theory predicts that the mass is so large and gives at least one possible theoretical idea that might solve the problem.
From the video description:
With the discovery of what looks to be the Higgs boson, LHC researchers are turning their attention to the next big question, which is the predicted mass of the newly discovered particles. When the effects of quantum mechanics is taken into account, the mass of the Higgs boson should be incredibly high…perhaps upwards of a quadrillion times higher than what was observed.
Dr. Don Lincoln also asks: why is the HJiggs Bosson so light?
