论文摘要
在具有较大的中央电荷的强耦合保形场理论中,重要的自由度是应力张量及其复合材料,多应力张量。我们考虑在热状态和重状态下应力张量的两点函数的OPE扩展,并专注于四个时空维度中应力张量和双重压力张量的贡献。我们将结果与全息有限温度的两点函数进行比较,并在大中央电荷扩展中读取超出领先顺序的共形数据。特别是,我们对确定相关因子近光酮行为的OPE系数进行了校正。我们还计算了双重张量操作员的异常尺寸。
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 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 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.
