We prove that N = 2 theories that arise by taking n free hypermultiplets and gauging a subgroup of Sp(n), the non-R global symmetry of the free theory, have a remaining global symmetry which is a direct sum of unitary, symplectic, and special orthogo

A common feature of many string-motivated particle physics models is additional strongly coupled U(1)'s. In such sectors, electric and magnetic states have comparable mass, and integrating out modes also charged under U(1) hypercharge generically yie

We describe an infinite two-parameter subfamily of theories of class $$ \mathcal{S} $$ where dialing one of the parameters interpolates between Gaiotto’s T N theory and a theory of N 2 free hypermultiplets. After using the reduced superconformal in

We explore new IR phenomena and dualities, arising for product groups, in the context of N = 1 supersymmetric gauge theories. The RG running of the multiple couplings can radically affect each other. For example, an otherwise IR interacting coupling

In earlier work, we (KI and BW) gave a two line "almost proof" (for supersymmetric RG flows) of the weakest form of the conjectured 4d a-theorem, that a_{IR}

An exact and general solution is presented for a previously open problem. We show that the superconformal R-symmetry of any 4d SCFT is exactly and uniquely determined by a maximization principle: it is the R-symmetry, among all possibilities, which (

We compute four-derivative corrections to the AdS supergravity actions arising from the near-horizon geometry of N M5-branes wrapped on either one or two Riemann surfaces. This setup features the novel presence of both gauged isometries as well as no

We develop a general set of methods for computing the oblique electroweak parameters S andT for bottom-up and top-down motivated scenarios in which the Higgs weakly mixes with a superconformal extra sector. In addition to their utility in phenomenolo

We construct a large new family of four-dimensional $ \mathcal{N}=1 $ superconformal field theories by coupling Gaiotto’s T N theories to $ \mathcal{N}=1 $ vector multiplets. In particular, we consider theories in which various T N blocks are linke

Gauge mediated models of supersymmetry breaking often exhibit 'gaugino screening,' where to leading order in F, gaugino masses are unaffected by higher dimensional Kahler potential interactions between the supersymmetry breaking spurion and the messe
