Description
Using the QCD equations of motion in the quark sector, Lorentz symmetry and discrete symmetries, one can derive an expression of partonic angular momentum in which the total, J, orbital, L, and spin, S components can be associated with specific twist two and twist three Generalized Parton Distributions. Within this approach, the different terms are derived using nonlocal matrix elements only, emphasizing the role of transverse momentum-spin correlations. I will discuss the angular momentum decomposition obtained in this approach for both the longitudinal and transverse cases.
