Regge residues and supermultiplets

We adopt biquark and triquark Regge propagators βØ(p+μ)⊗(p-μ)Γ[1-α Ø](α′s)αø-1 and βψ(p+m)⊗(p+m)⊗(p+m)Γ[ 3 2-αψ](α′s)αψ 3 2 with constant residues, to describe meson and baryon exchange. This leads to conventional polynomial residues and permits excellent extrapolation from hadron pole to scattering regions (e.g., Δ), as well as automatically providing cross-over points. © 1971.
