Abstract

We start by observing that the light-ray operators featured in the conformal collider literature are celestial primaries. This allows us to rephrase the corresponding 4D CFT correlators as probing a conformally soft matter sector of the 2D celestial CFT (CCFT). To demonstrate the utility of this perspective we show how the recent w1+w_{1+\infty} symmetry observed in CCFT suggests a natural extension of the conformal collider operators.
