For an unpolarized target, the generalized parton distribution H q (x, 0, t) is related to the distribution of partons in impact parameter space. The transverse distortion of this distribution for a transversely polarized target is described by E q (x, 0, t). * This work was supported by the DOE (DE-FG03-95ER40965) 2 We will suppress the scale (i.e. Q 2 ) dependence of these matrix elements for notational convenience. In the end, the ⊥ 'resolution' will be limited by 1/Q.
