CURRENT EXPERIMENTAL STATUS OF NEUTRINO OSCILLATION

Compelling evidence for neutrino oscillation was obtained from the Super-Kamiokande's observation of atmospheric neutrinos with Δm² ~ 10^-3 eV². There are two other indications of neutrino oscillation with different Δm² from solar neutrino observations and the LSND experiment. On the other hand, an important bound was obtained by the CHOOZ reactor neutrino oscillation experiment. The results from these experiments as well as some other neutrino oscillation experiments are reviewed. Particular emphasis is placed on the recent results from Super-Kamiokande, which were updated in June, 2000. In addition, the status of the K2K experiment and the prospects of forthcoming neutrino oscillation experiments are reviewed.
