O. Yasuda, 3-FLAVOR NEUTRINO OSCILLATION ANALYSIS OF THE SUPERKAMIOKANDE ATMOSPHERIC NEUTRINO DATA - ART. NO. 091301, Physical review. D. Particles and fields, 5809(9), 1998, pp. 1301
SuperKamiokande atmospheric neutrino data for 535 days are analyzed in
the framework of three flavor oscillations with mass hierarchy. It is
shown that the best fit point is very close to the pure maximal nu(mu
) <-> nu(tau) case and Delta m(2) similar or equal to 7 X 10(-3) eV(2)
. The allowed region at 90% C.L. is given and the implications to the
long baseline experiments are briefly discussed. [S0556-2821(98)50619-
