Double-Regge-Pole Analysis ofπ+p→π+ϱ0pat13.1GeVc

A double-Regge-exchange analysis of the reaction ${\pi }^{+}p\to {\pi }^{+}{\rho }^{0}p$ at $13.1\frac{\mathrm{GeV}}{c}$ is presented. The events are divided into proton diffractive (∼80%) and pion diffractive (∼20%) categories, each of which requires two double-Regge amplitudes for a complete description. The data of each sample are well described by a double-Regge model consistent with duality.
