Abstract
Long baseline neutrino experiments are moving towards the era of precision measurements. As they continue to collect data, systematic uncertainties will become the dominant source of uncertainties in their measurements. The work presented in this thesis focuses on neutrino-nucleus interactions, one of the primary sources of uncertainty for neutrino oscillation measurements.
This thesis describes the first simultaneous measurement of the muon neutrino charged current cross-section for interactions with and without a charged pion in the final state using the T2K ND280 detector. This measurement uses a log-likelihood method to extract the cross-section. The cross-section extracted were found to be $\sigma_{CC0\pi} = (5.43 \pm 0.37)\times10^{-39} \text{cm}^{2}\text{nucleon}^{-1}$ and
$\sigma_{CC1\pi^+} = (2.16 \pm 0.33)\times10^{-39} \text{cm}^{2}\text{nucleon}^{-1}$.
Finally, a comparison to the latest T2K results was performed, which showed that the measured cross-section in this thesis was higher than the latest results published by T2K, as well as a comparison to the NEUT generator and the T2K tuned cross-section model showing good agreement in well constrained region of the phase space but larger discrepancies in the extended phase space region used in the analysis presented in this thesis.
