Spin-Orbit Dynamics from the Gluon Asymmetry
Gordon P. Ramsey, Yev Binder, Dennis Sivers
Determination of the orbital angular momentum of the proton is a difficult but important part of understanding fundamental structure. Insight can be gained from suitable models of…
Probing the Orbital Angular Momentum through the Polarized Gluon Asymmetry
Gordon P. Ramsey
The orbital angular momentum is one of the least understood of the spin characteristics of a proton. There are no direct ways to model the orbital angular momentum. However, the Jz…
Polarized Parton Distributions for Spin Asymmetries
Gordon P. Ramsey
We have used QCD and polarized deep-inelastic scattering data to construct x-dependent polarized parton distributions. These flavor dependent distributions evolve under the NLO DGL…
Nucleon Spin Distributions From Recent SMC, SLAC and DESY Data
Gordon P. Ramsey, Mehrdad Goshtasbpour
We have extracted polarized nucleon distributions from recent data at CERN, SLAC and DESY. The flavor-dependent valence and sea quark spin distributions are determined for each exp…
