Four-point correlators of light-ray operators in CCFT

High Energy Physics - Theory 2022-08-10 v1

Abstract

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)(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.
