Universality of soft theorem from locality of soft vertex operators
The universal behavior of the soft theorem at the tree level is explained by considering the operator product expansion of the soft and hard vertex operators. We find that the world-sheet integral for the soft vertex is determined only by the regions that are close to the hard vertices after elimina...
