# Anisotropic string tensions and inversely magnetic catalyzed deconfinement from a dynamical AdS/QCD model

## TL;DR

This paper investigates how an external magnetic field affects QCD phenomena like deconfinement and string tension using a dynamical AdS/QCD model, revealing inverse magnetic catalysis and anisotropic confinement effects.

## Contribution

It introduces an analytic Einstein-Maxwell-dilaton solution with a magnetic field to study QCD observables, extending previous models with new insights into magnetic effects.

## Key findings

- Inverse magnetic catalysis observed in deconfinement transition.
- Anisotropic string tension with weaker confinement perpendicular to the magnetic field.
- Qualitative agreement with lattice QCD results.

## Abstract

We extend previous work on dynamical AdS/QCD models by introducing an extra ingredient under the form of a background magnetic field, this to gain insight into the influence such field can have on crucial QCD observables. Therefore, we construct a closed form analytic solution to an Einstein-Maxwell-dilaton system with a magnetic field. We specifically focus on the deconfinement transition, reporting inverse magnetic catalysis, and on the string tension, reporting a weaker/stronger confinement along/perpendicular to the magnetic field. The latter, being of importance to potential modelling of heavy quarkonia, is in qualitative agreement with lattice findings.
