Pion momentum distributions in the nucleon in chiral effective theory
M. Burkardt, K. S. Hendricks, Chueng-Ryong Ji +2
We compute the light-cone momentum distributions of pions in the nucleon in chiral effective theory using both pseudovector and pseudoscalar pion-nucleon couplings. For the pseudov…

Parton Orbital Angular Momentum and Final State Interactions
Matthias Burkardt
Definitions of orbital angular momentum based on Wigner distributions are used as a framework to discuss the connection between the Ji definition of the quark orbital angular momen…
