Abstract

We summarize the next-to-leading order (NLO) corrections to next-to-eikonal (NEik) quark background contributions to DIS structure functions. At NEik accuracy, in addition to corrections arising from the gluon background field of the target, DIS structure functions receive contributions from the t-channel quark exchanges, represented by insertions of the quark background field of the target. The latter provide the lowest order contributions in αs at NEik accuracy. We show that the NLO corrections to the longitudinal NEik structure functions are finite, whereas those to the transverse NEik structure functions exhibit rapidity and ultraviolet (UV) divergences. We analyze these divergences and extract the finite contributions.
