Breakup of hadron masses and the energy-momentum tensor of QCD
Breakup of hadron masses and the energy-momentum tensor of QCD
Hadron masses are shown to be separable in QCD into contributions of quark and gluon kinetic and potential energies, quark masses, and the trace anomaly. The separation is based on a study of the structure of the QCD energy-momentum tensor and its matrix elements in hadron states. The paper contains …
