The role of dRGT mass terms in cutoff holography and the Randall--Sundrum II scenario

TL;DR

This paper explores how $T^2$ deformations in holographic CFTs relate to massive gravity and demonstrates their connection to the Randall--Sundrum II brane-world scenario, revealing new insights into holography and gravity models.

Contribution

It establishes a link between $T^2$ deformations, ghost-free massive gravity, and the Randall--Sundrum II scenario, providing a novel perspective on holographic dualities.

Findings

$T^2$ deformation arises from coupling to massive gravity

Equations match those of Randall--Sundrum II in a certain approximation

Provides a new holographic interpretation of brane-world models

Abstract

We show how the $T^2$ deformation of large $N$, holographic conformal field theories arise from coupling them to the quadratic mass term of ghost-free massive gravity. We then show that in a certain approximation, the equations arising from the variation of the background frame field are those of the Randall--Sundrum II scenario.
