Nuclear suppression of heavy quark production at forward rapidities in relativistic heavy ion collisions

TL;DR

This paper investigates how heavy quark production is suppressed in high-energy nucleus collisions, considering shadowing and energy loss effects in Quark Gluon Plasma at RHIC and LHC, to understand the underlying mechanisms.

Contribution

It provides a detailed calculation of nuclear suppression factors for charm and bottom quarks, incorporating shadowing and various energy loss models at different rapidities.

Findings

Suppression varies with rapidity and energy loss mechanisms.

Results can help distinguish between different energy loss models.

Provides predictions for charm and bottom quark suppression at RHIC and LHC.

Abstract

We calculate nuclear suppression $R_{AA}$ of heavy quarks produced from the initial fusion of partons in nucleus-nucleus collisions at RHIC and LHC energies. We take the shadowing as well as the energy loss suffered by them while passing through Quark Gluon Plasma into account. We obtain results for charm and bottom quarks at several rapidities using different mechanisms for energy loss, to see if we can distinguish between them.
