Landscape of Simple Superconformal Field Theories in 4D
Abstract
We explore the space of renormalization group flows that originate from supersymmetric N =1 S U (2 ) gauge theory with one adjoint and a pair of fundamental chiral multiplets. By considering all possible relevant deformations—including coupling to gauge-singlet chiral multiplets—we find 34 fixed points in this simple setup. We observe that theories in this class exhibit many novel phenomena: emergent symmetry, decoupling of operators, and narrow distribution of central charges a /c . This set of theories includes two of the N =2 minimal Argyres-Douglas theories and their mass deformed versions. In addition, we find 36 candidate fixed point theories possessing unphysical fermionic operators—including one with central charges (a ,c )≃(0.20 ,0.22 ) that are smaller than any known superconformal theory—that need further investigation.
