Quark Correlations and Single Spin Asymmetries
Matthias Burkardt
We analyze the Sivers asymmetry in light-cone gauge. The average transverse momentum of the quark distribution is related to the correlation between the quark distribution and the…
Sivers Asymmetry and Generalized Parton Distributions in Impact Parameter Space
Matthias Burkardt, Dae Sung Hwang
Recently, it has been pointed out that there exists a connection between the generalized parton distribution and the Sivers asymmetry. For transversely polarized nucleon…
Chromodynamic Lensing and Single Spin Asymmetries
Matthias Burkardt
The physical interpretation of generalized parton distributions (in the limit ) as Fourier transforms of impact parameter dependent parton distributions is discussed. Particul…
Some Inequalities for the Generalized Parton Distribution E(x,0,t)
Matthias Burkardt
We discuss some constraints on the and -dependence of that arise from positivity bounds in the impact parameter representation. In addition, we show that $E(x,0,0…
Chromodynamic Lensing and Transverse Single Spin Asymmetries
Matthias Burkardt
We illustrate how an axial asymmetry in impact parameter dependent parton distributions can give rise to an axial asymmetry for the transverse momentum of the leading quark in the…
