Current Correlators and AdS/CFT Geometry
Edwin Barnes, Elie Gorbatov, Ken Intriligator +1
We consider current-current correlators in 4d SCFTs, and also 3d SCFTs, in connection with AdS/CFT geometry. The superconformal symmetry of the SCFT has th…
The Exact Superconformal R-symmetry Minimizes
Edwin Barnes, Elie Gorbatov, Ken Intriligator +2
We present a new, general constraint which, in principle, determines the superconformal symmetry of 4d SCFTs, and also 3d SCFTs. Among all possibilities, t…
N=1 RG Flows, Product Groups, and a-Maximization
Edwin Barnes, Ken Intriligator, Brian Wecht +1
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 a…
Evidence for the Strongest Version of the 4d a-Theorem, via a-Maximization Along RG Flows
Edwin Barnes, Ken Intriligator, Brian Wecht +1
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}<a_{UV}, using our resu…
