Gauging Discrete Symmetries of $T_N$-theories in Five Dimensions.
2021
We study the gauging of a discrete $\Z_3$ symmetry in the five-dimensional superconformal $T_N$ theories. We argue that this leads to an infinite sequence of five-dimensional superconformal theories with either $E_6 \times SU(N)$ or $SU(3)\times SU(N)$ global symmetry group. In the $M$-theory realisation of $T_N$ theories as residing at the origin in the Calabi-Yau orbifolds ${\C^3 \over {\Z_N \times \Z_N}}$ we identify the $\Z_3$ symmetry geometrically and the new theories arise from $M$-theory on the non-Abelian orbifolds $({\C^3 \over {\Z_N \times \Z_N}})/{\Z_3}$. On the other hand, in the $(p,q)$ 5-brane web description in Type IIB theory, the symmetry combines the $U$-duality symmetry with a rotation in space, defining a so-called $U$-fold background, where the $E_6$ symmetry is manifest.
