Abstract
Understanding the proton mass in quantum chromodynamics (QCD) is a very important and current topic in hadronic physics. The decomposition (sum rule) of the proton mass is not unique, and different sum rules, which are related to the QCD energy-momentum tensor, can be found in the literature. We review and compare these sum rules and identify open questions in this field.

Report
The manuscript presents the understanding of the decomposition of the proton mass in QCD in terms of contributions from quarks and gluons which is a topic of high interest and fundamental importance. It elaborates on the proper expressions for the renormalized operators of the mass decomposition using diagonal and minimal-subtraction-type schemes.
The text is well-written and is certainly worth publishing.
