# Parton correlations effects in double parton distribution functions

## TL;DR

This paper discusses the calculation of double parton distribution functions (dPDFs) and their potential to reveal three-dimensional partonic structures within protons through phenomenological analysis relevant for upcoming LHC experiments.

## Contribution

It presents new calculations of dPDFs and explores their impact on measurable observables, advancing understanding of parton correlations inside protons.

## Key findings

- dPDFs can be calculated and modeled
- Observable effects of parton correlations are identified
- Potential for experimental estimation at the LHC

## Abstract

Double parton distribution functions (dPDFs), measurable in hadron-hadron collisions and encoding information on how partons inside a proton are correlated among each other, could represent a new tool to explore the three dimensional partonic structure of hadrons. In the present contribution, results of the calculations of dPFDs are presented. Phenomenological calculations of experimental observables, sensitive to dPDFs are also discussed showing how double parton correlations could be estimated in the next LHC run.
