The Tokai to Kamioka (T2K) experiment in Japan is designed to investigate neutrino oscillations. A beam of muon neutrinos is produced at the J-PARC facility in Tokai. The beam’s flux, composition, energy spectrum and interaction cross section are measured 280 m downstream of the production point using a suite of near detectors. These are measured again 295 km away at the Super-Kamiokande detector. By comparing these two measurements, oscillation parameters can be obtained.
As it is possible for decay photons from neutral pions to be mis-identified as electron neutrino events in the Super-Kamiokande detector, it is important that we clearly understand the mechanisms by which these are produced. The seminar will focus on selecting muon neutrino charged-current π0 interactions which occur in the ND280 off-axis detector. These interactions will be investigated by selecting events where a muon is produced in one of the Fine-Grained detectors (FGD) and the decay photons from the π0 are identified using the Electromagnetic Calorimeter (ECal) and the Time Projection Chambers (TPCs). Discriminating variables and selection criteria used in the analysis will be described, along with suggestions for future work.Add to my calendar
