Pion Transparency in 500 MeV C(pi,pi') Reactions?

Abstract

The question whether there is a pion transparency in 500 MeV $C(\pi ,{\pi }^{{}^{\prime }})$ scatterings is studied using a semiclassical, hadronic transport model. The double differential cross sections of this reaction measured at LAMPF can be largely accounted for, if one uses energy-dependent, anisotropic angular distributions which are fitted to pion-nucleon scattering data for the decay of $\Delta (1232)$ and $N^{\ast }(1440)$ resonances. The remaining discrepancy between the data and the calculation sets a limit on effects of more exotic processes.
