5D SCFTs from C3 Orbifolds

Jiahua Tian

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 Γ 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.
