Description

Hadronic matrix elements of the QCD energy-momentum tensor can be parametrized in terms of gravitational form factors (GFFs), which encode information about mechanical properties of the hadron like the spatial distributions of energy, pressure, and shear forces. GFFs can be constrained indirectly by experiments through their relation with generalized parton distributions (GPDs), but they are directly and straightforwardly accessible to lattice calculations. We present the results of recent lattice calculations of the GFFs in the proton, including a complete calculation of both quark and glue contributions, and use them to derive spatial densities.
