Gravitational form factors and mechanical properties of a quark at one loop in light-front Hamiltonian QCD
arXiv:2112.06550 · doi:10.1103/PhysRevD.105.056017
Abstract
We calculate the gravitational form factors (GFFs) and pressure, shear and energy distributions for a quark state dressed with a gluon at one loop in QCD. We use the light-front Hamiltonian approach. In the light-front gauge, we use a two-component formalism to eliminate the constrained fields. The state may be thought of as a perturbative model for a relativistic spin composite system having a gluonic degree of freedom. We compare the results with model calculations for a nucleon.
