Four-point correlators of light-ray operators in CCFT

bstract 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.
