Fluctuations and the clustering of color sources

TL;DR

This paper investigates how fluctuations in particle multiplicity and transverse momentum at LHC energies are influenced by the clustering of color sources, showing that fluctuations relate to the number of formed clusters.

Contribution

It introduces a clustering model of color sources to explain multiplicity and pT fluctuations, providing a new perspective on particle production mechanisms at high energies.

Findings

Fluctuations are proportional to the number of color source clusters.

Clustering modifies the effective number of sources involved in particle production.

The model aligns with observed fluctuation patterns at LHC energies.

Abstract

We present our results on multiplicity and $p_T$ fluctuations at LHC energies in the framework of the clustering of color sources. In this approach, elementary color sources -strings- overlap forming clusters, so the number of effective sources is modified. We find that the fluctuations are proportional to the number of those clusters.
