Heavy quark potential from deformed $AdS_5$ models

TL;DR

This paper explores the heavy quark potential within various deformed AdS_5 holographic models, revealing a consistently negative potential across all quark-antiquark distances using a novel renormalization approach.

Contribution

It introduces a generalized method for calculating the heavy quark potential in deformed AdS_5 models, extending previous specific models and highlighting the impact of a new renormalization scheme.

Findings

Potential is negative definite for all separations

Different from results using traditional renormalization

Applicable to a broad class of deformed AdS_5 models

Abstract

In this paper, we investigate the heavy quark potential in some holographic QCD models. The calculation relies on a modified renormalization scheme mentioned in a previous work of Albacete et al. After studying the heavy quark potential in Pirner-Galow model and Andreev-Zakharov model, we extend the discussion to a general deformed $AdS_5$ case. It is shown that the obtained potential is negative definite for all quark-antiquark separations, differs from that using the usual renormalization scheme.
