Multigraviton Scattering in the Matrix Model

TL;DR

This paper investigates multigraviton scattering in the matrix model, revealing discrepancies with supergravity predictions and discussing potential sources for these differences.

Contribution

It identifies a mismatch between matrix model calculations and supergravity results for three-to-three graviton scattering processes.

Findings

Discrepancy observed between matrix model and supergravity amplitudes.

Discussion of potential reasons for the amplitude mismatch.

Highlights need for further investigation into matrix model predictions.

Abstract

We consider scattering processes in the matrix model with three incoming and three outgoing gravitons. We find a discrepancy between the amplitude calculated from the matrix model and the supergravity prediction. Possible sources for this discrepancy are discussed.
