Crossing symmetric dispersion relations in QFTs and CFTs

Abstract: I will discuss crossing symmetric dispersion relations in QFTs and CFTs. I will talk about connections with Polyakov’s 1974 work, the crossing symmetric Polyakov-Mellin bootstrap, and connections with fixed-t dispersion relations. I will also talk about generalized Froissart bounds in QFTs which follow from this approach.
