Back-to-back dijet production in DIS at next-to-eikonal accuracy and twist-3 gluon TMDs

Tolga Altinoluk, Guillaume Beuf, Alina Czajka +1

We consider dijet production in deep inelastic scattering at small $x$, on a purely gluonic unpolarized target. Starting from earlier results obtained at next-to-eikonal accuracy i…
