Long range forward-backward rapiditiy correlations in proton-proton collisions at LHC

TL;DR

This paper proposes that string percolation explains the flat rapidity distribution and constant forward-backward correlation in proton-proton collisions at LHC energies, providing specific predictions for different collision energies.

Contribution

It introduces string percolation as the underlying mechanism for observed rapidity correlations and makes novel predictions for LHC proton-proton collision outcomes.

Findings

Flat rapidity distribution explained by string percolation

Constant forward-backward correlation parameter predicted

Specific predictions for LHC energies at 14 TeV and 5.5 TeV

Abstract

We argue that string percolation is in the origin of i) an approximately flat rapidity distribution and of ii) an approximately constant forward-backward correlation parameter $b$ over a substantial fraction of the available rapidity. Predictions are given for $pp$ collisions at LHC, $\sqrt{s}=14$TeV and $\sqrt{s}=5.5$TeV.
