Description

This talk introduces a model for classical gauge field correlators in a large hadronic medium beyond the eikonal approximation. We incorporate plus and transverse components, which are absent in the eikonal approach, while disregarding the $x^{-}$-dependence of the field. Our model facilitates the analytical computation of the cross section for quark-antiquark (dijet) production in nuclear Deep Inelastic Scattering (DIS). Focused on the kinematic region with relatively high momenta of the quark-antiquark pair, where the classical field is dilute, we conduct numerical evaluations specifically in electron-gold collisions. Additionally, we compare our results with those in the transverse momentum-dependent (TMD) framework and in the dense limit of the Color Glass Condensate (CGC) at the eikonal level.
