Controversy concerning the definition of quark and gluon angular momentum

Journal Article Leader, Elliot - Physical Review. D, Particles Fields

A major controversy has arisen in QCD as to how to split the total angular momentum into separate quark and gluon contributions, and as to whether the gluon angular momentum can itself be split, in a gauge-invariant way, into a spin and orbital part. Several authors have proposed various answers to these questions and offered a variety of different expressions for the relevant operators. I argue that none of these is acceptable and suggest that the canonical expression for the momentum and angular momentum operators is the correct and physically meaningful one. It is then an inescapable fact that themore »« less

Quark and Gluon Angular Momentum in the Nucleon

Journal Article Burkardt, Matthias ; BC, Hikmat ; Jarrah, Abdullah - AIP Conference Proceedings

Parton distributions in impact parameter space, which are obtained by Fourier transforming GPDs, are exhibit a significant deviation from axial symmetry when the target and/or quark is transversely polarized. From this deformation, we present an intuitive derivation of the Ji relation. In a scalar diquark model and in QED, we compare the Ji and Jaffe-Manohar decompositions of the nucleon spin. Using the MIT bag model, we estimate spectator effects through the presence of the gluon vector potential in the definitions of the quark orbital angular momentum.

QCD evolution of the orbital angular momentum of quarks and gluons: Genuine twist-three part

Journal Article Hatta, Yoshitaka ; Yao, Xiaojun - Physics Letters. B

We present the numerical solution of the one-loop QCD evolution equation for the genuine twist- three part of the orbital angular momentum (OAM) distributions of quarks and gluons inside a longitudinally polarized nucleon. This is based on the observation that the evolution is identical to that of the Efremov-Teryaev-Qiu-Sterman function for transverse single spin asymmetry. Together with the known evolution of the Wandzura-Wilczek part, the one-loop evolution of OAM distribu- tions is now practically under control. We also study, for the rst time, the scale dependence of the potential angular momentum dened as the dierence between the Ji and Jae-Manoharmore » denitions of OAM.« less
