Angular momentum distribution for a quark dressed with a gluon: different decompositions

We present a recent calculation of the quark and gluon contributions to the angular momentum of a composite spin -$1\mathrm{/}2$ state in QCD. The state we consider is a quark dressed with a gluon, and we use the two-component framework in light-front Hamiltonian QCD. We compare the results from different decompositions available in the literature. We also present the angular momentum distributions.
