Energy-momentum tensor in QCD: nucleon mass decomposition and mechanical equilibrium

Abstract We review and examine in detail recent developments regarding the question of the nucleon mass decomposition. We discuss in particular the virial theorem in quantum field theory and its implications for the nucleon mass decomposition and mechanical equilibrium. We reconsider the renormaliza...
