Clarification of longitudinal and transverse spin sum rules
Proper definition of canonical orbital angular momentum
Analysis of spin-orbit correlation in nucleons
Abstract
We briefly review the spin structure of the nucleon and show that it is best thought in the light-front formulation. We discuss in particular the longitudinal and transverse spin sum rules, the proper definition of canonical orbital angular momentum and the spin-orbit correlation.
