Elliptic flow of heavy flavors

TL;DR

This paper models the elliptic flow of heavy flavor quarks in quark-gluon plasma, incorporating energy loss mechanisms, and successfully reproduces experimental data while predicting flow at different collider energies.

Contribution

It introduces a unified formalism for heavy quark energy loss and elliptic flow, applicable across different collision energies and experiments.

Findings

Reproduces experimental elliptic flow data for non-photonic electrons.

Predicts elliptic flow of heavy mesons at LHC and RHIC energies.

Accounts for radiative and collisional energy dissipation mechanisms.

Abstract

The propagation of charm and bottom quarks through an ellipsoidal domain of quark gluon plasma has been studied within the ambit of non-equilibrium statistical mechanics. Energy dissipation of heavy quarks by both radiative and collisional processes are taken in to account. The experimental data on the elliptic flow of the non-photonic electrons resulting from the semi-leptonic decays of hadrons containing heavy flavours has been reproduced with the same formalism that has been used earlier to reproduce the nuclear suppression factors. The elliptic flow of the non-photonic electron from heavy meson decays produced in nuclear collisions at LHC and low energy RHIC run have also been predicted.
