Abstract
Tokai-to-Kamioka (T2K) is a long baseline neutrino osciallation experiment. A high intensity beam of muon neutrinos is produced at the Japan Proton Accelerator Research Complex (J-PARC) and travels 295 km across Japan towards the Super-Kamiokande (SuperK) water Cherenkov detector. A suite of near detectors (ND280) is located 280 m downstream of the production point and contained within a 0.2 T dipole magnet. The Pi-Zero Detector (P∅D) is a component of the near detector complex. The P∅D is designed to constrain the π0 background at SuperK, and is optimized to detect electromagnetic showers. It is composed of alternating layers of plastic scintillator and water targets which can be drained or filled, allowing for measurements in both a “water-in” and “water-out” configuration. The neutrino beam is directed 2.5 o off-axis to produce a flux peaked at ∼600 MeV at the near
and far detectors. For this paper, the total beam used is 2.5 x 10 20 protons on target (p.o.t) for water-in running, and 3.6 x 10 20 p.o.t for water-out. This thesis will present the selection for a P∅D-contained charged-current 0-pion (CC-0π) single-track sample in both water-in and water-out modes. This selection is the first
P∅D-specific analysis to be implemented fully in the ND280 analysis framework, Highland2. Several tools were developed to determine the directionality of P∅D tracks, and this selection is also the first P∅D analysis to use the full angular phase-space of the out-going muon. A Bayesian unfolding engine is then used to calculate the double differential CC-0π cross-section on water. The results are presented in bins of the reconstructed muon momentum,
pμ, and angle from the neutrino direction, cos(θμ) for both data and Monte Carlo fake data.
