AB We present a new method to systematically include corrections to the eikonalapproximation in the background field formalism. Specifically, we calculate the subleading,power-suppressed corrections due to the finite width of the target or the finite energy of theprojectile. Such power-suppressed corrections involve Wilson lines decorated by gradientsof the background field — thus related to the density - of the target. The method is ofgeneric applicability. As a first example, we study single inclusive gluon production in pAcollisions, and various related spin asymmetries, beyond the eikonal accuracy
