Generalized Parton Distributions and Distribution of Partons in the Transverse Plane

Abstract

I discuss the physical interpretation of GPDs in the limit $\xi =0$, where the $t$ dependence contains information about the distribution of partons in the transverse plane. GPDs thus allow a simultaneous determination of the longitudinal momentum and transverse position of partons in the infinite momentum frame, which also provides a physical interpretation for Ji's angular momentum sum rule.
