Talk Title:  “Scattering in Quantum Gravity and the Conformal Bootstrap ”

Abstract:

The AdS/CFT correspondence reveals a profound harmony between emergent structures in quantum gravity and the dynamics of quantum field theories with many degrees of freedom. Among the most fundamental quantities in gravity are scattering amplitudes, which are equivalent to correlation functions in the dual field theory. I will describe new approaches to computing these observables, using modern techniques at the interface of gravity and field theory. In gravity, I will introduce simple, geometric computations of tree-level scattering in AdS; in conformal field theory, I will use the equations of the conformal bootstrap, a research program that aims to delineate the space of consistent theories solely using abstract symmetry principles, to derive non-planar correlation functions that are dual to loop amplitudes in gravity. I will discuss the promise of these ideas to address a wider range of problems, within and without AdS/CFT. An overarching theme will be the pursuit of an answer to a basic question: what is a holographic conformal field theory?
