Heavy quark potential and jet quenching parameter in a rotating D-instanton background

TL;DR

This paper investigates how rotation, instanton density, and temperature affect heavy quark potential and jet quenching in a holographic model, revealing that rotation and temperature promote quark pair dissociation and increase jet quenching, while instanton density suppresses dissociation.

Contribution

It introduces a rotating D-instanton background to study heavy quark potential and jet quenching, highlighting the effects of angular velocity and instanton density on these phenomena.

Findings

Angular velocity and temperature promote quark-antiquark dissociation.

Instanton density suppresses quark-antiquark dissociation.

Jet quenching parameter increases with angular velocity, instanton density, and temperature.

Abstract

We get the dual gravity metric of the rotating nuclear matter by performing a standard Lorentz transformation on the static metric in the D-instanton background. Then, we study the effects of the angular velocity, the instanton density and the temperature on the heavy quark potential. It is shown that the angular velocity and the temperature promote dissociation of the quark-antiquark pair, and the instanton density suppresses dissociation. Similarly, according to the result of the jet quenching parameter, we found that the jet quenching parameter increases with the increase of angular velocity, instanton density and temperature, and the jet quenching parameter in the rotating D-instanton background is larger than that of N = 4 SYM theory.
