TL;DR

This paper investigates how a deformation parameter in a deformed AdS background influences the holographic Schwinger effect, particularly the pair production rate and electrostatic potential, with implications for testing AdS/QCD.

Contribution

It introduces the effect of a deformation parameter on the electrostatic potential and pair production rate in a deformed AdS background, expanding understanding of holographic Schwinger effect.

Findings

Larger deformation parameter reduces the separation length of test particles.

Presence of a finite maximum separation length due to the deformation.

Deformation parameter impacts the pair production rate in the holographic setup.

Abstract

In this paper, we consider a deformed AdS background and study effect of deformation parameter on the pair production rate of the Schwinger effect. The electrostatic potential is important for the pair production in the holographic Schwinger effect. In this paper, we analyze the electrostatic potential in a deformed AdS background and investigate the effect of deformation parameter which may be useful to test of AdS/QCD. In the case of zero temperature we find that larger value of the deformation parameter leads to a smaller value of separation length of the test particles on the probe. Also we find a finite maximum of separation length in presence of modification parameter.
