Regge Poles and the Pauli Principle

In a Regge-pole model of large-angle $\mathrm{pp}$ scattering, Huang and Pinsky take the Pauli principle into account by adding $t$- and $u$-channel Regge poles. We point out that this procedure is consistent with the finite-energy sum rules. In a recent note, Pinsky points out some regularities in the experimental data and contends that they favor a different model in dealing with the Pauli principle, namely, some kind of "duality" between the $t$ and $u$ channels. We show that the regularities he noticed are also reproduced by the original "additive" model.
