Abstract In strongly coupled conformal field theories with a large central charge important light degrees of freedom are the stress tensor and its composites, multi-stress tensors.We consider the OPE expansion of two-point functions of the stress tensor in thermal and heavy states ps5 price new jersey and focus on the contributions from the stress tensor and double-stress tensors in four spacetime dimensions.We compare the results to the holographic finite life extension blueberry extract temperature two-point functions and read off conformal data beyond the leading order in the large central charge expansion.In particular, we compute corrections to the OPE coefficients which determine the near-lightcone behavior of the correlators.We also compute the anomalous dimensions of the double-stress tensor operators.
