Intermittency analysis of $pp$ collisions at $\sqrt{s}=$ 0.9, 7 and 8 TeV from the CMS experiment

TL;DR

This study applies the scaled factorial moments method to analyze intermittency in proton-proton collisions at different energies from the CMS experiment, revealing energy-dependent trends in intermittency strength.

Contribution

It introduces an intermittency analysis of $pp$ collisions at multiple energies using the Bialas and Peschanski method on CMS data, highlighting energy-dependent behaviors.

Findings

Intermittency strength decreases with increasing energy in 1D analysis.

Intermittency is stronger in 2D but shows no clear energy trend.

Results suggest weakening of the $eta$-model signature at higher energies.

Abstract

The method of horizontal scaled factorial moments as outlined by Bialas and Peschanski was used to conduct intermittency analysis for $pp$ collisions at $\sqrt{s}=$ 0.9, 7 and 8 TeV from the CMS experiment. The data was obtained and processed from the CERN Open Data Portal. It was found from 1D analysis that the intermittency strength decreases with increasing energy, indicating that the signature of the $\alpha$-model of random cascading that the former is based on seems to be weakening. Intermittency was stronger in 2D, but did not reveal any clear trend with increasing collision energy.
