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&times10<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 &plusmn 0.15 (stat) &plusmn 0.14 (sys)."},{"label":"dcterms.available","value":"2015-04-24T14:47:03Z"},{"label":"dcterms.contributor","value":"Weinacht, Thomas"},{"label":"dcterms.creator","value":"Lopez, Glenn David"},{"label":"dcterms.dateAccepted","value":"2015-04-24T14:47:03Z"},{"label":"dcterms.dateSubmitted","value":"2013-05-22T17:35:08Z"},{"label":"dcterms.description","value":"Department of Physics"},{"label":"dcterms.extent","value":"134 pg."},{"label":"dcterms.format","value":"Application/PDF"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/1951/59768"},{"label":"dcterms.issued","value":"2012-05-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2013-05-22T17:35:08Z (GMT).
