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

TL;DR

This study analyzes intermittency fluctuations in proton-proton collisions at different energies, revealing that the strength of these fluctuations diminishes as collision energy increases, indicating a weakening of the underlying multiparticle cascade process.

Contribution

It provides the first detailed analysis of intermittency exponents in high-energy pp collisions at LHC energies, showing energy-dependent behavior of fluctuation patterns.

Findings

Intermittency exponents decrease with increasing collision energy.

Cascading multiparticle production weakens at higher energies.

Results suggest a change in the underlying particle production dynamics.

Abstract

The intermittency-type fluctuations as outlined by Bialas and Peschanski in the 1980s is analysed in $pp$ collisions at $\sqrt{s}=$ 0.9, 7 and 8 TeV from the CMS collaboration at CERN. Our preliminary analysis shows that the intermittency exponents in the bin-averaged scaled factorial moments decrease in magnitude with increasing collision energy at the TeV scale, which suggests that the cascading nature of multiparticle production described by the $\alpha$-model is weakening. We outline possible areas planned for future studies.
