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

Elastic proton-proton scattering is studied at high energies. It is shown that at large angles the data is fitted by $\frac{d\nu }{d\Omega }=s^{-1\mathrm{}}K\left(t\right)\mathrm{}{\left(\frac{\nu }{s_0}\right)}^{2\alpha \mathrm{}\left(t\right)\mathrm{}}$, where $\nu =\frac{1}{2}\mathrm{}(s-u)\mathrm{}$, 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.
