Classification of rank one 5d $\mathcal{N}=1$ and 6d $(1,0)$ SCFTs

Abstract: This paper gives a classification of rank one 5d $\mathcal{N}=1$ and 6d $(1,0)$ SCFTs. The idea is to compactify 5d theory on $S^1$ and 6d theory on $T^2$ to get effective 4d $\mathcal{N}=2$ theory. These compactified theories all have a 4d $\mathcal{N}=2$ Coulomb branch whose solution can be described by mixed Hodge module (MHM). In the rank one case every Coulomb branch solution is related to rational elliptic surface with a section, whose classification is complete. So the classification is then reduced to pick up a subset from the data base of rational elliptic surface by imposing various physical constraints. The crucial new input is that the singular fiber at infinity determines which dimension the UV theory lives. Various physical properties such as flavor symmetry, one form symmetry, BPS quiver and BPS spectrum, and RG flow are studied. D7 brane configurations for those theories are found which are very useful in studying them. The generalizations to higher rank theories will also be highlighted.
