# Flux-tubes in confining gauge theories with gravitational dual

## TL;DR

This paper investigates the formation and properties of flux-tubes in a confining gauge theory using gauge/gravity duality, focusing on their shape, fluctuations, and impact on quark potential.

## Contribution

It provides a detailed analysis of flux-tube shapes and fluctuations in a 3D confining gauge theory via holographic methods, linking string dynamics to quark confinement.

## Key findings

- Flux-tubes are modeled as classical open strings in the bulk.
- Fluctuations in flux-tube thickness are related to string fluctuations in the radial direction.
- The shape of flux-tubes influences the heavy quark potential.

## Abstract

The emergence of flux-tubes as the distance is increased between a quark and an antiquark is explored in a three-dimensional confining gauge theory using the gauge/gravity duality. We delineate the shape of the flux-tube corresponding to the classical open string in the bulk and further explore the fluctuation in its thickness induced by the fluctuation of the open string along the radial direction in the bulk. The relationship between the intrinsic shape of a flux-tube and its effect on the heavy quark potential is also discussed.
