Beyond a = c : gravitational couplings to matter and the stress tensor OPE
Abstract We derive constraints on the operator product expansion of two stress tensors in conformal field theories (CFTs), both generic and holographic. We point out that in large N CFTs with a large gap to single-trace higher spin operators, the stress tensor sector is not only universal, but isola...
