A Quantum-Mechanical Model for the M5-Brane

Abstract

We present a maximally supersymmetric extension of the BFSS matrix model based on the 5-Lie algebra ๐’œ6. The theory is Lagrangian, promotes the BFSS 2-bracket structure constants to dynamical objects governed by a Chern-Simons-like kinetic term, and displays features expected from a theory of M5-branes. We show that it can also be obtained from the single lightcone M5-brane action on a spatial five-sphere after a truncation to the time coordinate. The resulting theory is a consistent truncation and, analogously to the U(2) BFSS model, supports an interpretation of the ๐’œ6 theory as a quantum-mechanical model for the lowest-lying modes of the M5-brane.

AB  - We present a maximally supersymmetric extension of the BFSS matrix model based on the 5-Lie algebra ๐’œ_6. The theory is Lagrangian, promotes the BFSS 2-bracket structure constants to dynamical objects governed by a Chern-Simons-like kinetic term, and displays features expected from a theory of M5-branes.
