Bounds on 4D conformal and superconformal field theories

We derive general bounds on operator dimensions, central charges, and OPE coefficients in 4D conformal and superconformal field theories. In any CFT containing a scalar primary ϕ of dimension d we show that crossing symmetry of implies a completely general lower bound on the central charge c ≥ f c (...
