Perspective on the Origin of Hadron Masses

The energy–momentum tensor in chiral QCD, T μ ν , exhibits an anomaly, viz. Θ 0 : = T μ μ ≠ 0 . Measured in the proton, this anomaly yields m p 2 , where m p is the proton’s mass; but, at the same time, when computed in the pion, the answer is m π 2 = 0 . Any attempt to understand the origin and nat...
