Multiple M5-branes, String 2-connections, and 7d nonabelian Chern-Simons theory
Multiple M5-branes, String 2-connections, and 7d nonabelian Chern-Simons theory
The worldvolume theory of coincident M5-branes is expected to contain a nonabelian 2-form/nonabelian gerbe gauge theory that is a higher analog of self-dual Yang-Mills theory.But the precise details -in particular the global moduli / instanton / magnetic charge structure -have remained elusive.Here we deduce from anomaly cancellation a natural candidate …
