# ITMD factorization and broadening effects in production of forward di-jets

## TL;DR

This paper compares forward di-jet correlations in proton-proton and proton-lead collisions to ITMD factorization calculations, highlighting the importance of gluon saturation and Sudakov effects for accurate data description.

## Contribution

It demonstrates the necessity of including both gluon saturation and Sudakov resummation effects within the ITMD framework to accurately describe forward di-jet correlation data.

## Key findings

- Gluon saturation and Sudakov effects are essential for modeling di-jet broadening.
- ITMD factorization effectively describes the azimuthal correlations.
- Comparison with ATLAS data confirms the theoretical approach.

## Abstract

I report on the recent result of comparison of forward-forward dijet correlations in azimuthal angle as measured by the ATLAS collaboration in the proton-proton and proton-lead collisions to calculations within ITMD factorization framework [1]. The comparison shows that the broadening effect due to interplay of both the gluon saturation and the Sudakov resummation is necessary to describe the data.
