Exteneded Longitudinal Scaling and the Thermal Model

TL;DR

This paper demonstrates that the statistical thermal model explains extended longitudinal scaling in rapidity distributions across various energies, but predicts a violation at LHC energies due to new phenomena.

Contribution

It shows the consistency of the thermal model with experimental data up to RHIC energies and predicts a breakdown of scaling at LHC energies.

Findings

Thermal model aligns with rapidity distributions at RHIC energies.

Extended longitudinal scaling is expected to break down at LHC energies.

The property of scaling is not universal at the highest energies.

Abstract

The property of extended longitudinal scaling of rapidity distributions was noticed recently over a broad range of beam energies. It is shown here that this property is consistent with predictions of the statistical thermal model up to the highest RHIC beam energies, however, we expect that at LHC energies the rapidity distribution of produced particles will violate extended longitudinal scaling.
