Open heavy flavor and J/psi at RHIC and LHC within a transport model

TL;DR

This paper uses a transport model to study the production and evolution of heavy quarks and J/psi particles in quark-gluon plasma at RHIC and LHC, comparing results with experimental data and making predictions.

Contribution

It introduces a comprehensive transport model that includes interactions among all partons and applies it to analyze heavy flavor and J/psi production in heavy-ion collisions.

Findings

Model successfully reproduces experimental elliptic flow and nuclear modification factors.

Provides predictions for observables where data is not yet available.

Reports on J/psi elliptic flow considering dissociation and regeneration processes.

Abstract

The production and space-time evolution of heavy quarks and J/psi in the quark gluon plasma is studied within the partonic transport model Boltzmann Approach to MultiParton Scatterings (BAMPS). This framework allows interactions among all partons: gluons, light quarks and heavy quarks. Heavy quarks, in particular, interact with the rest of the medium via binary scatterings with a running coupling and a more precise Debye screening which is derived from hard thermal loop calculations. We compare our results of the elliptic flow and nuclear modification factor not only to experimental data of heavy flavor electrons at RHIC, but also to LHC data of heavy flavor electrons, muons, D mesons, and non-prompt J/psi. Where no data is available yet, we make predictions for those observables. Furthermore, results on prompt J/psi elliptic flow are reported for RHIC energy within the same framework, taking the dissociation as well as regeneration of J/psi in the quark-gluon plasma into account.
