Does the suppression shown at LHC in O-O collisions follow the systematics obtained for A-A collisions ?

TL;DR

This paper investigates whether the suppression of neutral pions in oxygen-oxygen collisions at the LHC aligns with established systematics from heavier nucleus-nucleus collisions, finding good agreement in suppression patterns.

Contribution

It demonstrates that recent O-O collision data follow the same suppression systematics as heavier A-A systems, extending the applicability of these systematics.

Findings

O-O collision suppression matches A-A systematics

Experimental R_{AA} values agree with predictions

Supports universality of suppression patterns across systems

Abstract

In this paper we present to what extent recent experimental results obtained for $\pi^{0}$ suppression in O-O collisions at $\sqrt{s_{NN}}$=5.36 TeV fit into the systematics for much heavier systems. The systematics with which the comparison is made was published a few years ago \cite{Pet_1} in terms of charged particles suppression $R_{AA}$ as a function of $\langle N_{part} \rangle$ and $\langle dN_{ch}/d\eta \rangle$. The values of $R_{AA}$ at $\langle dN_{ch}/d\eta\rangle$ and $\langle N_{part} \rangle$ experimentally measured and estimated by Glauber MC, respectively, for O-O collisions are in good agreement with the systematics obtained for A-A collisions.
