The exact superconformal R-symmetry minimizes image Original Research Article

We present a new, general constraint which, in principle, determines the superconformal image symmetry of 4d image SCFTs, and also 3d image SCFTs. Among all possibilities, the superconformal image is that which minimizes the coefficient, image, of its two-point function. Equivalently, the superconformal image is the unique one with vanishing two-point function with every non-R flavor symmetry. For 4d image SCFTs, image minimization gives an alternative to a-maximization. image minimization also applies in 3d, where no condition for determining the superconformal image had been previously known. Unfortunately, this constraint seems impractical to implement for interacting field theories. But it can be readily implemented in the AdS geometry for SCFTs with AdS duals.
