Conformal blocks from celestial gluon amplitudes. Part II. Single-valued correlators
Abstract In a recent paper, here referred to as part I, we considered the celestial four-gluon amplitude with one gluon represented by the shadow transform of the corresponding primary field operator. This correlator is ill-defined because it contains branch points related to the presence of conform...
