The S-matrix Bootstrap for a Custodially-Symmetric Higgs

Abstract: The S-matrix bootstrap uses analyticity, unitarity, and crossing symmetry to place nonperturbative bounds on 4-point scattering amplitudes. In my talk, I describe the application of the bootstrap to the scattering of O(4) symmetric scalars, an approximation to the Higgs boson in the custodial limit, explain what we are able to learn about amplitudes in the allowed region, and discuss how current experimental constraints on Higgs self-interactions can manifest in the bootstrap space.
