论文摘要
我们计算了两个Gluon轻射算子和两个Gluon Primaries的四点相关器，该相关器来自$（2,2）$签名时空的四聚体天体振幅。相关器是非分布的，允许我们验证光射线操作员出现在两个Gluon Primaries的OPE中。我们还对涉及Gluon操作员交换的术语进行了保形块分解。
We compute the four-point correlator of two gluon light-ray operators and two gluon primaries from the four-gluon celestial amplitude in $(2,2)$ signature spacetime. The correlator is non-distributional and allows us to verify that light-ray operators appear in the OPE of two gluon primaries. We also carry out a conformal block decomposition of the terms involving the exchange of gluon operators.
