Regge-Pole Formulas for Differential Cross Sections of Quasi-Two-BodyπNandNNInteractions

Abstract

Regge-pole formulas for differential cross sections of some quasi-two-body $\pi N$ and $\mathrm{NN}$ interactions, which can have one or two meson trajectories exchanged, are given in this paper. The reactions treated are: $\pi N\to \pi \Delta \mathrm{}\left(1236\right)\mathrm{}$, $\pi N\to \omega \Delta \mathrm{}\left(1236\right)\mathrm{}$, $\pi N\to A_{2}N$, $\pi N\to \eta N$, $\pi N\to \eta \Delta \mathrm{}\left(1236\right)\mathrm{}$, $\pi N\to \rho N$, $\pi N\to \rho \Delta \mathrm{}\left(1236\right)\mathrm{}$, $\mathrm{NN}\to N\Delta \mathrm{}\left(1236\right)\mathrm{}$, $\mathrm{NN}\to N{N}^{*}(1500,{\frac{3}{2}}^{-})$, $\mathrm{NN}\to N{N}^{*}(1480,{\frac{1}{2}}^{+})$.
