The D-Term: Pressure To Find The Last Item On The Checklist

The D-term is an interesting property of matter that has received a comparatively small amount of research dedicated to it compared to other global properties such as mass and spin. We discuss its potential connection to pressure and shear force distributions inside the nucleon, and provide possible means of extracting this form factor both theoretically and experimentally. We also provide a model calculation of both the A-term and D-term in $\phi^3 $ theory, which required the modification of the energy-momentum tensor from its canonical definition to a renormalized "Improved" energy-momentum tensor.
