Description

For the DIS dijet cross section at low x, Next-to-Eikonal power corrections with respect to the Shockwave/CGC result have been calculated (at LO in alpha_s). In this talk, we will present the expansion of that result in the back-to-back dijet limit, keeping terms of twist 2 or 3. This allows us to check the consistency between the Shockwave/CGC formalism and the TMD factorization formalism beyond leading power in both ways: beyond eikonal accuracy in the Regge limit and beyond twist 2 in the Bjorken limit for back-to-back dijet. In particular, we find the x dependence of the TMDs to be recovered from non-eikonal power corrections.
