The Contribution of Regge Cuts on π[sup 0] Photoproduction from Complex Nuclei within 4 to 12 GeV

Abstract

The contribution of Regge cuts on the incoherent π 0 photoproduction cross section from complex nuclei is investigated at forward angles within 4 to 12 GeV. The calculations are performed using two different parameterizations (with and without Regge cuts) for the elementary photoproduction cross section and the multicollisional intranuclear cascade model (MCMC) to address the nuclear effects. The results indicate that the influence of the Regge cuts is negligible and the nuclear cross section (shape and magnitude) is strongly constrained by short range correlations and meson-nucleus Final State Interactions.
