M-theory Beyond The Supergravity Approximation

TL;DR

This paper investigates the four-point function in a 6d quantum field theory dual to M-theory on AdS7×S4, deriving leading corrections beyond supergravity and exploring higher-spin solutions.

Contribution

It provides the first derivation of M-theoretic corrections to supergravity predictions using crossing equations and superconformal partial waves.

Findings

Derived the leading correction analogous to $\\mathcal{R}^4$ in string theory.

Identified higher-spin solutions that are subleading to 1-loop supergravity.

Established a framework for analyzing quantum corrections in M-theory via conformal bootstrap.

Abstract

We analyze the four-point function of stress-tensor multiplets for the 6d quantum field theory with $OSp(8^*|4)$ symmetry which is conjectured to be dual to M-theory on $AdS_7 \times S^4$, and deduce the leading correction to the tree-level supergravity prediction by obtaining a solution of the crossing equations in the large-$N$ limit with the superconformal partial wave expansion truncated to operators with zero spin. This correction corresponds to the M-theoretic analogue of $\mathcal{R}^4$ corrections in string theory. We also find solutions corresponding to higher-spin truncations, but they are subleading compared to the 1-loop supergravity prediction, which has yet to be calculated.
