In this paper we demonstrate that at the core, the geometry is given by the convex hull of the product of two moment curves.

We analyze so-called generalized Veneziano and generalized Virasoro amplitudes. Under some physical assumptions, we find that their spectra must satisfy an over-determined set of non-linear recursion relations. The recursion relation for the generalized Veneziano amplitudes can be solved analytically and yields a two … WebDec 31, 2024 · This forces the infinite tower of higher-dimension operators to lie inside a new geometry we call the "EFThedron".
