Abstract

The NEUT intranuclear cascade model is described and fit to a large body of π± -nucleus scattering data. Methods are developed to deal with deficiencies in the available historical data, and robust uncertainty estimates are produced. The results are compared to a variety of simulation packages and the data. This work provides a method for tuning final state interaction models, which are of particular interest to neutrino experiments that operate in the few-GeV energy region, and provides results which can be used directly by the T2K and Super-Kamiokande Collaborations, for whom NEUT is the primary simulation package.
