The Exact Superconformal R-symmetry Minimizes ${\tau }_{RR}$

Edwin Barnes, Elie Gorbatov, Ken Intriligator +2

We present a new, general constraint which, in principle, determines the superconformal $U(1{)}_R$ symmetry of 4d $\mathbb{N}=1$ SCFTs, and also 3d $\mathbb{N}=2$ SCFTs. Among all possibilities, t…
