Title: The O(N) Monolith reloaded: Sum rules and Form Factor Bootstrap

Abstract: In this talk I will present the S-matrix bootstrap program and its application to the study of 2d gapped and UV complete QFTs. In our work we extend the known results from pure S-matrix bootstrap by including into the set-up form factors and spectral functions of the stress energy tensor and conserved currents. I will explain how this extended set-up works and show how the associated sum rules allows us to put bounds on quantities like the central charge of the underlying conformal theories in the UV. In this context I will show how from our results a big portion of the boundary of the space of allowed theories can only flow from CFTs with infinite central charges. I will track this result down to a particular behaviour of the amplitudes in physical kinematics and discuss its physical implications. Based on arxiv:hep-th/2311.03031 in collaboration with L. Córdova, M. Correia and A. Vuignier.
