Description
We investigate different decompositions of angular momentum in QCD for a relativistic spin 1/2 composite state, specifically a quark dressed with a gluon. We employ light-front Hamiltonian perturbation theory developed in the light-front gauge and utilize a two-component framework that eliminates constrained degrees of freedom. Our investigation extends to various decompositions of angular momentum, examining two-dimensional densities in the light-front formalism, and considers the impact of potential terms. We contrast these decompositions with other literature findings and explore the gravitational form factor associated with the antisymmetric part of the energy-momentum tensor. Additionally, we verify angular momentum sum rules to ensure consistency
