Magnetic Catalysis for Heavy Quarks in Anisotropic Holographic Model

TL;DR

This paper enhances a holographic model to better understand magnetic catalysis in heavy quarks within anisotropic quark-gluon plasma, revealing how spatial anisotropy affects phase transition temperatures.

Contribution

It introduces modifications to an existing holographic model to accurately capture magnetic catalysis phenomena for heavy quarks, incorporating anisotropy and magnetic field effects.

Findings

Spatial anisotropy lowers the transition temperature across magnetic field values.

Modified warp factor and coupling function improve the model's description of magnetic catalysis.

The model aligns with lattice results for heavy quark magnetic catalysis.

Abstract

We consider a twice anisotropic five-dimensional holographic model supported by Einstein-dilaton-three-Maxwell action that was constructed in the paper [arXiv:2011.07023]. Although, that model reproduced some essential features of the ``heavy quarks'', but did not describe the magnetic catalysis (MC) phenomenon expected from lattice results for the Quark-Gluon Plasma (QGP) with heavy quarks. We study MC phenomenon as well as typical properties of the heavy quarks phase diagram contains magnetic field as a new parameter by improving the holographic model, i.e. modifying the ``heavy quarks'' warp factor and the coupling function for the Maxwell field. Considering spatial anisotropy decreases the transition temperature for all values of the magnetic field for heavy quarks model.
