Soft QGP probes with ALICE

TL;DR

This paper reviews ALICE experiment measurements of soft probes in various collisions at the LHC, focusing on flow, femtoscopy, and the properties of the Quark-Gluon Plasma through low transverse momentum particle analysis.

Contribution

It presents recent flow measurements, femtoscopic studies, and the first preliminary analysis of K0sK± femtoscopy in heavy-ion collisions at the LHC.

Findings

Flow measurements indicate collective behavior in the QGP.

Femtoscopic studies provide insights into the spatial and temporal characteristics of particle emission.

First preliminary analysis of K0sK± femtoscopy offers new data on particle correlations.

Abstract

In heavy-ion collisions at the LHC a hot and dense medium of deconfided partons, the Quark-Gluon Plasma (QGP), is created. Its global properties can be characterized by the measurements of particles in the low transverse momentum (or "soft") regime, which represent the majority of created particles. In this report we outline a selection of measurements of the soft probes by the ALICE experiment in pp, p--Pb, and Pb--Pb collisions. The paper focuses on recent flow measurements via angular correlations and femtoscopic studies. The first ever preliminary analysis of $\mathrm{K}^0_{\rm S}\mathrm{K}^{\pm}$ femtoscopy is also presented.
