Description
We will present updated results on three-flavor atmospheric neutrino oscillation from the Super-Kamiokande experiment, covering the 373 kt-year exposure of Super-K I through IV. Atmospheric neutrinos cover a wide energy range, are comprised of both neutrinos and antineutrinos, have both electron and muon flavors, oscillate into a significant tau neutrino component, and experience matter effects in the earth. Through a detailed 3-flavor analysis this data is sensitive to the neutrino mass hierarchy, the octant of theta-23, and the CP-violating phase as well as beyond the standard model interactions. The data analysis presented has been updated to include improvements in event reconstruction and modeling of neutrino-nucleus interactions.
