A bstractWe carry out a detailed superspace analysis of the OPE of two N=2$$\mathcal{N}=2$$ stress-tensor multiplets. Knowledge of the multiplets appearing in the expansion, together with the two-dimensional chiral algebra description of N=2$$\mathcal{N}=2$$ SCFTs, imply an analytic bound on the central charge c. This bound is valid for any N=2$$\mathcal{N}=2$$ SCFT regardless of its matter content and flavor symmetries, and is saturated by the simplest Argyres-Douglas fixed point. We… Expand
