论文摘要
操作员产品扩展是表示相关函数的有用工具。在本说明中，我们扩展了共形雷格理论，以提供保形场理论中洛伦兹四点相关因子的精确OPE表示，甚至有效地远离了regge限制。该表示形式通过将OPE作为在连续的旋转和尺寸上重写的双重积分来扩展了OPE的收敛性，并具有新颖的“ Regge Block”。我们在共形渔网理论中测试了公式，其中可用涉及非平凡的regge轨迹的确切结果。
The Operator Product Expansion is a useful tool to represent correlation functions. In this note we extend Conformal Regge theory to provide an exact OPE representation of Lorenzian four-point correlators in conformal field theory, valid even away from Regge limit. The representation extends convergence of the OPE by rewriting it as a double integral over continuous spins and dimensions, and features a novel "Regge block". We test the formula in the conformal fishnet theory, where exact results involving nontrivial Regge trajectories are available.
