Monopole deformations of 3d Seiberg-like dualities with adjoint matters

Abstract

Abstract We propose new 3d N $$ \mathcal{N} $$ = 2 Seiberg-like dualities by considering various monopole superpotential deformations on 3d N $$ \mathcal{N} $$ = 2 U(N c ) SQCDs with fundamental and adjoint matter fields. We provide nontrivial evidence of these new dualities by comparing the superconformal indices, from which we analyze the change of the moduli space due to the monopole deformation. In addition, we perform the F-maximization to check the relevance of the monopole deformation for some examples, one of which is found to exhibit nontrivial symmetry enhancement in the IR. We prove such enhancement of the global symmetry using the superconformal index.
