Anisotropic flow: A case for Bottomonia

TL;DR

This paper discusses the potential of bottomonia, especially $mbda(1S)$, as a cleaner probe for quark-gluon plasma (QGP) through anisotropic flow measurements, highlighting its advantages over charmonia studies.

Contribution

It introduces the idea of using bottomonia anisotropic flow as a novel and cleaner probe for QGP, emphasizing the need for further studies in small systems.

Findings

Bottomonia, particularly $mbda(1S)$, can serve as a new probe for QGP.

Charmonia $v_2$ studies have advanced understanding of charm quark thermalization.

Further studies are needed for small system collisions.

Abstract

Studies of $J/$$\psi$ $v_2$ at RHIC and LHC energies have provided important elements towards the understanding on the production mechanisms and on the thermalization of charm quarks. Bottomonia has an advantage since it is a cleaner probe. A brief discussion has been provided for $\Upsilon(1S)$ $v_2$, which can become the new probe for QGP, including the necessity of studies for small systems.
