Description
We compute the contribution of the quark and gluon component of the energy-momentum tensor (EMT) to the angular momentum density in various decompositions. We use the light-front Hamiltonian technique, and a two-component formalism in light-front gauge, where the constrained degrees of freedom are eliminated. Instead of a nucleon, we consider a simple composite spin-1/2 state, namely a quark dressed with a gluon. We present two-dimensional light-front distributions in transverse impact parameter space and compare the different angular momentum decompositions at the density level. We also verify the spin sum rule for such a state.
