Double Regge analysis and the extended Dolen-Horn-Schmid duality applied to the processes pp → Δ++π−p and pp → pp ω

Abstract

A simplified double Regge model analysis is applied down to threshold to the processes pp → Δ ++ π −p and pp → p ωp in order to test the extension of Dolen-Horn-Schmid duality proposed by Chew and Pignotti. This gives rather good agreement with experiment, and further leads to quantitative conclusions concerning relative couplings of different reggeons, and concerning the vertex functions. The meson-exchange coupling is found to be stronger than the Pomeron exchange in multi-Regge diagrams even at the highest accelerator energies available at present.
