Regge Behavior at Large Angles, and the Dolen-Horn-Schmid Duality in Elastic Proton-Proton Scattering

Abstract

Elastic proton-proton scattering is studied at high energies. It is shown that at large angles the data is fitted by $\frac{d\ensuremath{\nu}}{d\ensuremath{\Omega}}={s}^{\ensuremath{-}1}K(t){(\frac{\ensuremath{\nu}}{{s}_{0}})}^{2\ensuremath{\alpha}(t)}$, where $\ensuremath{\nu}=\frac{1}{2}(s\ensuremath{-}u)$, which indicates that Regge theory is good at all angles at high energy. We also show how to avoid double counting parallelling Dolen, Horn, and Schmid.
