Title | Bounding Effective Field Theories by bootstrap methods |
Abstract | We show how to use general assumptions of the unknown UV theory to constrain the IR physics. Specifically, we can consider causality and unitarity of the S-matrix to set up a bootstrap problem. By solving it with numerical optimisation methods, we obtain the allowed EFT coefficients which are consistent with a unitary and causal UV completion. We focus on the scattering of photons in four dimensions with and without gravity. Finally, we present a method to compute all partial waves for spinning particles in arbitrary dimensions. |
