Using world charged pion--nucleus scattering data to constrain an intranuclear cascade model

The NEUT intranuclear cascade model is described and fit to a large body of \pipm--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 itself. 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.

Measurement of $σ_{\mathrm{ABS}}$ and $σ_{\mathrm{CX}}$ of $π^+$ on carbon by DUET

The DUET Collaboration reports on the measurements of the absorption ($σ_{\mathrm{ABS}}$) and charge exchange ($σ_{\mathrm{CX}}$) cross sections of positively charged pions on carbon nuclei for the momentum range 201.6 MeV$/c$ to 295.1 MeV$/c$. The uncertainties on the absorption and charge exchange cross sections are $\sim$9.5\% and $\sim$18\%, respectively. The results are in good agreement with previous experiments. A covariance matrix correlating the 5 $σ_{\mathrm{ABS}}$ and 5 $σ_{\mathrm{CX}}$ measured data points is also reported

Measurement of absorption and charge exchange of $π^+$ on carbon

The combined cross section for absorption and charge exchange interactions of positively charged pions with carbon nuclei for the momentum range 200 MeV/c to 300 MeV/c have been measured with the DUET experiment at TRIUMF. The uncertainty is reduced by nearly half compared to previous experiments. This result will be a valuable input to existing models to constrain pion interactions with nuclei.
