Title:
Causality and Universality at Strong Coupling
Abstract:
Causality imposes constraints on the coupling constants in perturbative effective field theory, which have played a role in understanding scattering amplitudes, the a-theorem for renormalization group flows, and higher curvature corrections in quantum gravity. I will describe similar constraints on strongly interacting theories, then use them to derive the averaged null energy condition, and discuss the connection to emergent geometry at large N.
