High Energy Theory Seminar
The original S-matrix Bootstrap proposed by Chew, Mandelstam, and others was based on the idea that the S-matrix might be fully constrained by global symmetries, crossing, unitarity, and analyticity. Recently this approach was revived from a somewhat different point of view. Using the same constraints, one numerically maps out the space of allowed S-matrices. For two to two scattering, the allowed space is a convex space that, in certain cases, has vertices that can be identified with a quantum field theory of interest. In that case, the approach allows the numerical computation of the S-matrix without relying on the particular Lagrangian of the theory. In this talk I describe recent results we obtained using convex optimization techniques.
The talk is in 469 Lauritsen.
