Contribution

It presents updated experimental results confirming neutrino oscillations and discusses the reconstruction of Super-Kamiokande after damage, advancing neutrino physics research.

Findings

Strong evidence for neutrino oscillations from Super-Kamiokande

K2K results are consistent with Super-Kamiokande findings

Reconstruction efforts after detector damage are detailed

Abstract

This paper summarizes recent (as of SSI-02, in some cases updated in November, 2002) results from the Super-Kamiokande and K2K experiments. The interpretation of Super-Kamiokande results on atmospheric and solar neutrinos provides strong evidence for neutrino oscillations, hence non-zero neutrino mass. While statistics are still limited, K2K data are consistent with Super-Kamiokande results on neutrino oscillations. The effort to reconstruct Super-Kamiokande following a cascade of phototube implosions in November, 2001 is described. Plans for the future are also discussed.
