Higher symmetries of 5D orbifold SCFTs

Abstract

Most higher-dimensional superconformal field theories (SCFTs) are intrinsically strongly coupled and lack a Lagrangian description. Generally, these theories are defined as singular compactifications of string and M-theory, and the information about the SCFTs, e.g. higher-form symmetries, is encoded in the structure of the singularities. The authors manage to extract the higher form symmetries from generic, not necessarily isolated orbifold singularities for five-dimensional SCFTs and demonstrate their method in a number of explicit examples.
