Abstract: (Springer)
We construct a family of 4dN \mathcal{N} = 1 theories that we call Eρσ {E}_{\rho}^{\sigma } [USp(2N)] which exhibit a novel type of 4d IR duality very reminiscent of the mirror duality enjoyed by the 3dN \mathcal{N} = 4 Tρσ {T}_{\rho}^{\sigma } [SU(N)] theories. We obtain the Eρσ {E}_{\rho}^{\sigma } [USp(2N)] theories from the recently introduced E[USp(2N )] theory, by following the RG flow initiated by vevs labelled by partitions ρ and σ for two operators transforming in the antisymmetric representations of the USp(2N) × USp(2N) IR symmetries of the E[USp(2N)] theory. These vevs are the 4d uplift of the ones we turn on for the moment maps of T[SU(N)] to trigger the flow to Tρσ {T}_{\rho}^{\sigma } [SU(N)]. Indeed the E[USp(2N)] theory, upon dimensional reduction and suitable real mass deformations, reduces to the T[SU(N)] theory. In order to study the RG flows triggered by the vevs we develop a new strategy based on the duality webs of the T[SU(N)] and E[USp(2N)] theories.
