  We investigate the different decompositions of the angular momentum in QCD
for a relativistic spin $1/2$ composite state, namely a quark dressed with a
gluon. We use light-front Hamiltonian perturbation theory, and in the
light-front gauge, use the two-component framework by eliminating the
constrained degrees of freedom. We also investigate the different
decompositions of the angular momentum at the level of two-dimensional
densities in the front form, including the effect of the so-called potential
term. In this work, we consider the contribution coming from the quark part of
the energy-momentum tensor. We contrast the different decompositions and also
compare with other calculations in the literature. We also present the
gravitational form factor related to the antisymmetric part of the
energy-momentum tensor.
