TITLE: 5D SCFTs from C3 Orbifolds
ABSTRACT: In this talk, we will consider the orbifold singularities X = C3/Γ where Γ is a finite subgroup of SU(3). M-theory on X gives rise to a rich class of 5D SCFTs. We will study these SCFTs via 3D McKay correspondence which relates the group theoretical data of \Gamma to the physical properties of the 5D SCFT. We find some theories in this class can be obtained by gauging certain discrete symmetries in other 5D SCFTs. I will report on recent progress on relating 5D SCFTs to 4D electric-magnetic duality in a class of G2 compactification.
