Analysis of neutrino oscillation in three-flavor neutrinos

We analyze the solar, terrestrial and atmospheric neutrino experiments including Super-Kamiokande data using the three-flavor neutrinos framework and obtain the allowed region for parameters (Delta m(12)(2), sin(2) 2 theta(12), Delta m(23)(2), theta(13), theta(23)). In solar neutrino experiments, we obtain the large angle solution (Delta m(12)(2), sin(2) 2 theta(12)) = (4x10(-6) -7x10(-5) eV(2), 0.6-0.9) and small angle solution (3 x 10(-6) - 1.2 x 10(-5) eV(2), 0.003 - 0.01) for theta(13) = 0 degrees - 20 degrees. From the terrestrial and atmospheric neutrino experiments including the sub-GeV and multi-GeV zenith angle dependence in SuperKamiokande 535 days data, we found that the nu(mu)- nu(tau) mixing is large and the range of Delta m(23)(2) as 0.02 similar to 0.0002 eV(2). There is no significant difference between large theta(12) angle solution and small one.
