I’m trying to understand the prediction of the proton mass according to Quantum Chromodynamics (QCD). I know that the proton is composed of quarks and gluons, and that the mass of the proton is not simply the sum of the masses of these constituent particles.
I’ve read that only about 1% of the proton’s mass comes from the mass of the quarks (which their mass comes from interaction with the Higgs field), and the rest comes from the energy of the quarks and gluons inside the proton, as well as quantum effects. However, I’m having trouble finding a specific numerical prediction for the proton mass according to QCD.
Could someone please explain what the current QCD prediction for the proton mass is, and how this compares to the experimentally measured value? Any references to relevant research papers would also be appreciated.
