Description
We present a state-of-the art computation for forward dijets in proton-proton and proton-lead collisions at the LHC, using the kinematics of FCal ATLAS calorimeter and the planned FoCal extension of ALICE. We use the small-$x$ improved TMD (ITMD) formalism, together with collinearly improved TMD gluon distributions, full $b$-space Sudakov resummation
and discuss nonperturbative corrections due to hadronization and showers using the \Pythia\ Monte Carlo. We observe that forward dijets in proton-nucleus collisions at moderately low $p_T$ are excellent probes of saturation effects, as the Sudakov resummation does not alter the suppression of the cross section.
