Description
In T2K, neutrinos are observed via charged current quasi-elastic scattering (CCQE) interactions (\nu_{\mu}+n->\nu^{-}+p), as well as charged current single pion production (CC1\pi) (\nu_{\mu}+p->\mu^{-}+p+\pi^{+}). The \pi^{+} is free to interact inside and outside the nucleus via absorption (ABS) and charge exchange (CX: \pi^{+}->\pi^{0}) processes. If there is an unobserved pion, then the reconstructed neutrino energy is incorrect. Reducing the uncertainties on these cross-sections reduces the systematic uncertainties for neutrino oscillation measurements.
The DUET Experiment was conducted in the M11 \pi^{+} beam line at TRIUMF to address this issue. Both combined ABS+CX and separate CX cross section measurements for \pi^{+} with initial momentum in the range of 200~350 MeV/c will be presented. The impact of this measurement for oscillation analyses on T2K and future experiments will be discussed.
