Description
A number of different decompositions for the proton mass have been proposed in the literature. All of them can be expressed as matrix elements of operators related to the Energy-Momentum Tensor in quantum chromodynamics. We review and revisit these decompositions, by paying special attention to recent developments with regard to the renormalization of the energy-momentum tensor. We present numerical results for the various terms of the mass decompositions up to the third order in the strong coupling, discussing their scheme dependence.
