4d $$ \mathcal{N} $$=2 theories with disconnected gauge groups
Abstract
In this paper we present a beautifully consistent web of evidence for the existence of interacting 4d rank1 $$ \mathcal{N} $$ = 2 SCFTs obtained from gauging discrete subgroups of global symmetries of other existing 4d rank1 $$ \mathcal{N} $$ = 2 SCFTs. The global symmetries that can be gauged involve a nontrivial combination of discrete subgroups of the U(1) _{R}, lowenergy EM duality group SL(2,Z), and the outer automorphism group of the flavor symmetry algebra, Out(F ). The theories that we construct are remarkable in many ways: (i) two of them have exceptional F _{4} and G _{2} flavor groups; (ii) they substantially complete the picture of the landscape of rank1 $$ \mathcal{N} $$ = 2 SCFTs as they realize all but one of the remaining consistent rank1 SeibergWitten geometries that we previously constructed but were not associated to known SCFTs; and (iii) some of them have enlarged $$ \mathcal{N} $$ = 3 SUSY, and have not been previously constructed. They are also examples of SCFTs which violate the ShapereTachikawa relation between the conformal central charges and the scaling dimension of the Coulomb branch vev. Here, we propose a modification of the formulas computing these central charges from the topologically twisted Coulomb branch partition function which correctly compute them for discretely gauged theories.

4d $$ \mathcal{N}=1 $$ from 6d $$ \mathcal{N}=\left(1,0\right) $$ on a torus with fluxes
Compactifying N = (1, 0) theories on a torus, with additional fluxes for global symmetries, we obtain N = 1 supersymmetric theories in four dimensions. It is shown that for many choices of flux these models are toric quiver gauge theories with singlet fields. Particularly we compare the anomalies deduced from the description of the six dimensional theory and the anomalies of the quiver gauge theories. Also, we give predictions for anomalies of fourdimensional theories corresponding to general compactifi cations of M5branes probing C ^{2}/Z _{k} singularities.Cited by 4

$$ \mathcal{N}=1 $$ deformations and RG flows of $$ \mathcal{N}=2 $$ SCFTs
We study certain N=1 preserving deformations of fourdimensional N=2 superconformal field theories (SCFTs) with nonabelian flavor symmetry. The deformation is described by adding an N=1 chiral multiplet transforming in the adjoint representation of the flavor symmetry with a superpotential coupling, and giving a nilpotent vacuum expectation value to the chiral multiplet which breaks the flavor symmetry. This triggers a renormalization group flow to an infrared SCFT. Remarkably, we find classes of theories flow to enhanced N=2 supersymmetric fixed points in the infrared under the deformation. They include generalized ArgyresDouglas theories and rankone SCFTs with nonabelian flavor symmetries. Most notably, wemore »Cited by 12
