On energy-momentum tensors and proton structure

We discuss baryonic energy-momentum tensors (EMT). The quantum nature of the particle is reflected in the square of the components of the energy-momentum tensor being proportional to interior probability densities depending on dynamical intrinsic configuration variables. We exemplify by an approxima...

Description
Summary:We discuss baryonic energy-momentum tensors (EMT). The quantum nature of the particle is reflected in the square of the components of the energy-momentum tensor being proportional to interior probability densities depending on dynamical intrinsic configuration variables. We exemplify by an approximate protonic state from which we determine density distributions. We find a mass density vanishing at the centre.
