Quark correlations and single-spin asymmetries
Matthias Burkardt
We illustrate, in a semi-classical picture, how the Wilson line phase factor in gauge invariantly defined unintegrated parton density can lead to a nonzero single-spin asymmetry (S…

Sivers Mechanism for Gluons
Matthias Burkardt
We study T-odd gauge invariantly defined T-odd unintegrated gluon densities in QCD. The average momentum of the gluons in a polarized nucleon can be nonzero due to…

Generalized Parton Distributions for large
Matthias Burkardt
The -dependence of generalized parton distrbutions for is discussed. We argue that constituent quark models, where the -dependence for is through the produc…
