Conformal Invariance of the Transition Vertex $2\to 4$ gluons

Abstract

We show that the transition vertex: two reggeized gluons $\to$ four reggeized gluons is invariant under Möbius transformations. This provides an important step in defining a conformally invariant effective field theory for QCD in the Regge limit.
