Impact Parameter Dependent Parton Distributions and Transverse Single Spin Asymmetries
Matthias Burkardt
Generalized parton distributions (GPDs) with purely transverse momentum transfer can be interpreted as Fourier transforms of the distribution of partons in impact parameter space.…
Impact Parameter Space Interpretation for Generalized Parton Distributions
Matthias Burkardt
The Fourier transform of generalized parton distribution functions at xi=0 describes the distribution of partons in the transverse plane. The physical significance of these impact…
Position space interpretation for generalized parton distributions
Matthias Burkardt
For an unpolarized target, the generalized parton distribution is related to the distribution of partons in impact parameter space. The transverse distortion of this d…
Violation of Sum Rules for Twist-3 Parton Distributions
M. Burkardt, Y. Koike
Sum rules for twist-3 distributions are reexamined. Integral relations between twist-3 and twist-2 parton distributions suggest the possibility for a -function at . We conf…

Sudip K. Seal, Matthias Burkardt
To appear in the proceedings of The Phenomenology of Large N(c) QCD, Tempe, Arizona, 9-11 Jan 2002.
