Recent Results from Experiments Using the Super-Kamiokande Detector

Conference paper

Abstract

The Super-Kamiokande detector (SK) in Gifu prefecture, Japan is used by two currently running experiments: The Super-Kamioka nde experiment searching for neutrinos from the sun, cosmic ray interactions in the atmosphere, and astrophysical sources, and the K2K long-baseline neutrino oscillation experiment. The long-baseline experiment detects neutrinos produced as tertiary products of the 12GeV proton synchrotron (PS) at the Japanese laboratory for high energy physics, KEK. Results from both experiments axe presented. Oscillation analyses of both atmospheric and solar neutrino data axe updated to the current data set, and some view of astrophysical searches is given. A cursory data summary from the long-baseline experiment is given and some general statements about its consistency with various oscillation based hypotheses axe made. (Results from the long-baseline experiment are updated since presentation at the conference.) Results from searches for proton decay and nearby Supernovae axe omitted here because of space considerations.

Due to limited space, I have chosen to omit some background material in favor of including plots of updated data. I hope the references will be of use to amend this. Also, some of the theoretical contributions to these proceedings will undoubtedly cover much of the necessary physics background.
