Numerical Solution of the Evolution Equation for Orbital Angular Momentum of Partons in the Nucleon
O. Martin, P. Hagler, A. Schafer
The evolution of orbital angular momentum distributions within the radiative parton model is studied. We use different scenarios for the helicity weighted parton distributions and…

Evolution Equations for Higher Moments of Angular Momentum Distributions
P. Haegler, A. Schaefer
Based on a sumrule for the nucleon spin we expand quark and gluon orbital angular momentum operators and derive an evolution matrix for higher moments of the corresponding distribu…
