Abstract content

In the Tokai-to-Kamioka (T2K) oscillation analysis, electron (anti)neutrino candidates are both the signal channel and the largest background. As the neutrino oscillation community looks to the future with experiments such as Hyper-Kamiokande, the oscillation analyses become limited by systematic error. A detailed understanding of neutrino-nucleus interactions is therefore imperative to maximise future sensitivity. In 2014, the T2K experiment published a charged-current electron neutrino cross-section measurement using the off-axis near detector, ND280. This result is being updated with improved selections, increased statistics, the inclusion of antineutrinos and a more model-independent method of cross-section extraction. The poster focuses on the new charged-current electron neutrino and electron antineutrino samples, as well as the the control regions that are used to constrain the backgrounds.
