Transverse Force Imaging
Abstract
While twist-2 GPDs allow for a determination of the distribution of partons on the transverse plane, twist-3 GPDs contain quark-gluon correlations that provide information about the average transverse color Lorentz force acting on quarks. As an example, we use the nonforward generalization of gT(x), to illustrate how twist-3 GPDs can provide transverse position information about that force.
