# Broadening and saturation effects in dijet azimuthal correlations in p-p and p-Pb collisions at $\mathbf{\sqrt{s_{NN}}} = $ 5.02 TeV

## TL;DR

This paper shows that forward-forward dijet correlations in p-p and p-Pb collisions at 5.02 TeV are explained by a combination of gluon saturation and Sudakov logarithm resummation effects, highlighting the importance of both in modeling such phenomena.

## Contribution

It demonstrates that both gluon saturation and Sudakov effects are essential to accurately describe dijet azimuthal correlations in high-energy collisions.

## Key findings

- Data are consistent with combined saturation and Sudakov effects.
- Both effects are necessary for accurate theoretical description.
- Results support the significance of gluon saturation in small-x physics.

## Abstract

We demonstrate that the recent forward-forward dijet correlation data measured by the ATLAS collaboration for proton-proton and proton-lead collisions are consistent with the broadening effects due to both the gluon saturation and the resummation of large logarithms of the hard scale (the so-called Sudakov logarithms). We find that both effects are necessary to describe the experimental results.
