Flattening of the EFT-hedron: supersymmetric positivity bounds and the search for string theory
Abstract We examine universal positivity constraints on 2 → 2 scattering in 4d planar N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory with higher-derivative corrections. We present numerical evidence that the convex region of allowed Wilson coefficients (the “EFT-hedron”) flattens completel...
