An experimental review on elliptic flow of strange and multi-strange hadrons in relativistic heavy ion collisions

TL;DR

This paper reviews experimental measurements of elliptic flow for strange and multi-strange hadrons in relativistic heavy ion collisions, highlighting their role as probes of the early quark-gluon plasma phase at RHIC and LHC.

Contribution

It provides a comprehensive overview of elliptic flow data for strange hadrons, emphasizing their significance in understanding the early stages of heavy ion collisions.

Findings

Strange hadrons exhibit significant elliptic flow signals.

Multi-strange hadrons show early-stage collectivity.

Results support quark-gluon plasma formation.

Abstract

Strange hadrons, especially multi-strange hadrons are good probes for the early partonic stage of heavy ion collisions due to their small hadronic cross sections. In this paper, I give a brief review on the elliptic flow measurements of strange and multi-strange hadrons in relativistic heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC).
