Thermal width and entropic force of a moving quarkonia with charged deformed AdS background

TL;DR

This paper investigates how charge and deformation in a holographic AdS model influence the entropic force and thermal width of moving quarkonia, revealing that increased charge shortens meson dissociation length and deformation enhances entropic effects.

Contribution

It introduces a charged deformed AdS background to study the entropic force and thermal width of moving quarkonia, highlighting the effects of charge and deformation parameters.

Findings

Charge increases entropic force and decreases meson dissociation length.

Deformation of the background enhances entropic force and thermal width.

Dissociation length varies with deformation parameter, allowing arbitrary values.

Abstract

The entropic force and the imaginary part of potential experienced by a moving quarkonia in a plasma, are computed in a charged deformed AdS background by holography approaches. In that case, the axis of the moving quarkonia has an arbitrary angle with wind. We show that the charge in deformed AdS background deeply effect on the increasing entropic force and decreasing thermal width. So, the dissociation length of the meson becomes short when charge is increasing. In addition, the entropic force and thermal width are increased by the deformation of the space. Therefore the deformation parameter in such background leads us to find process with arbitrary dissociation length of quark- anti quark.
