Helicity poles and the triple-Regge vertex

We determine the location of helicity poles in terms of Regge poles by an examination of Misheloff's triple-Regge expansion in a special limiting case. For this case, we identify on general grounds the presence of two comparable asymptotic terms. In one term the helicity pole is at α₁; in the other it is at α₂+α₃ where α₁, α₂, and α₃ are the three trajectories occurring in the Misheloff formulation.
