| dcterms.abstract | The T2K experiment is a long baseline neutrino oscillation experiment designed for the primary goal of measuring &nu<sub>&mu</sub> \rarr &nu<sub>e</sub> oscillation, thereby providing a measurement of the neutrino mixing angle &theta<sub>13</sub>. To achieve this goal, a beam of muon neutrinos is produced at the Japanese Proton Accelerator Research Complex in Tokai, Japan and sent 295 kilometers across Japan towards the Super-Kamiokande detector. One of the major backgrounds of the &nu<sub>e</sub> appearance measurement is from neutral current &nu<sub>&mu</sub> interactions where a single &pi<super>0</super> is produced and the photons from the &pi<super>0</super> decay mimic the &nu<sub>e</sub> appearance signal. To constrain the uncertainty on this background, a &pi<super>0</super>-detector has been constructed as part of the T2K near detector facility at 280 meters from the proton beam target. This dissertation presents a measurement of the neutral current single &pi<super>0</super> (NC1&pi<super>0</super>) production cross section using 8.55×10<super>19</super> protons-on-target (POT) of T2K data. This is achieved by using pre-defined selection criteria to enhance the NC1&pi<super>0</super> signal events over background events in the invariant mass distribution of NC1&pi<super>0</super> candidate events. An extended likelihood fit is then performed on the data distribution to extract the number of signal events. We measure the ratio of the NC1&pi<super>0</super> production cross section normalized by the &nu<sub>&mu</sub> Charged-Current Inclusive interaction to be 0.81 ± 0.15 (stat) ± 0.14 (sys). | |
