Atomic classification of 6D SCFTs
We use F‐theory to classify possibly all six‐dimensional superconformal field theories
(SCFTs). This involves a two step process: We first classify all possible tensor branches …

6d conformal matter
A bstract A single M5-brane probing G, an ADE-type singularity, leads to a system which has
G× G global symmetry and can be viewed as “bifundamental”(G, G) matter. For the AN …
