Long-range multiplicity correlations in proton-proton collisions

TL;DR

This paper investigates long-range multiplicity correlations in proton-proton collisions using a two-source model, showing good agreement with experimental data and comparing it to a single-source model.

Contribution

It introduces a two-source model for long-range correlations in proton-proton collisions and compares its predictions with experimental data and a single-source model.

Findings

The two-source model agrees well with UA5 data at 200 GeV.

The two-source model captures the forward-backward correlations effectively.

Comparison shows differences between single-source and two-source models.

Abstract

The forward-backward long-range multiplicity correlations in proton-proton collisions are investigated in the model with two independent sources of particles: one left- and one right-moving wounded nucleon. A good agreement with the UA5 collaboration proton-antiproton data at the c.m. energy of 200 GeV is observed. For comparison the model with only one source of particles is also discussed.
