Query: Descendants in celestial CFT and emergent multi-collinear factorization   Multi-collinear factorization limits provide a window to study how locality
and unitarity of scattering amplitudes can emerge dynamically from celestial
CFT, the conjectured holographic dual to gauge and gravitational theories in
flat space. To this end, we first use asymptotic symmetries to commence a
systematic study of conformal and Kac-Moody descendants in the OPE of celestial
gluons. Recursive application of these OPEs then equips us with a novel
holographic method of computing the multi-collinear limits of gluon amplitudes.
We perform this computation for some of the simplest helicity assignments of
the collinear particles. The prediction from the OPE matches with Mellin
transforms of the expressions in the literature to all orders in conformal
descendants. In a similar vein, we conclude by studying multi-collinear limits
of graviton amplitudes in the leading approximation of sequential
double-collinear limits, again finding a consistency check against the leading
order OPE of celestial gravitons.
