Flavor symmetry of 5d SCFTs. Part I. General setup

A large class of 5d superconformal field theories (SCFTs) can be constructed by integrating out BPS particles from 6d SCFTs compactified on a circle. We describe a general method for extracting the flavor symmetry of any 5d SCFT lying in this class. For this purpose, we utilize the geometric engineering of 5d N = 1 theories in M-theory, where the flavor symmetry is encoded in a collection of non-compact surfaces.

Automated summary

A class of 5d superconformal field theories can be constructed by integrating out BPS particles from 6d SCFTs compactified on a circle. The flavor symmetry of these 5d SCFTs can be extracted using geometric engineering in M-theory.
