Bootstrapping M-theory orbifolds

Abstract

Abstract We analyze correlation functions of SU(k) × SU(2) F flavor currents in a family of three-dimensional N $$ \mathcal{N} $$ = 4 superconformal field theories, combining analytic bootstrap methods with input from supersymmetric localization. Via holographic duality, we extract gluon and graviton scattering amplitudes of M-theory on AdS4 × S 7/ℤ k which contains a ℂ2/ℤ k orbifold singularity. From these results, we derive aspects of the effective description of M-theory on the orbifold singularity beyond its leading low energy limit. We also determine a threshold correction to the holographic correlator from the combined contribution of two-loop gluon and tree-level bulk graviton exchange.
