Particle Theory Seminar: Petar Tadic, Yale University, “Stress tensor sector of Holographic CFTs”

The stress tensor sector in holographic CFTs corresponds to multi-graviton contributions to correlation functions in dual AdS theory. In this talk, we will show how one can use the lightcone bootstrap to fix the dynamical data of multi-stress tensors with spin greater then 2, i.e. their operator product expansion (OPE) coefficients with external scalar operators. We will show that a subset of stress tensor sector that consists of operators with minimal twist, have OPE coefficients that do not depend on the choice of holographic CFT and are therefore universal. We will also discuss the behavior of the stress tensor sector in CFTs at finite temperature.
