| Abstract: | We suggest a simple modification of the maximal mixing scenario (withS 3 permutation symmetry) for three light neutrinos. Our neutrino mass matrix has smaller permutation symmetryS 2(ν μ ?ν e ), and is consistent with all neutrino experiments except the37Cl experiment. The resulting mass eigenvalues for three neutrinos arem 1≈(2.55?1.27)×10?3eV,m 2,3≈(0.71?1.43)eV for Δm LSND 2 =0.5?2.0eV2. Then these light neutrinos can account for ～(2.4?4.8)% (6.2?12.4%) of the dark matter forh=0.8 (0.5). Our model predicts theν μ →ν τ oscillation probability in the range sensitive to the future experiments such as CHORUS and NOMAD. |
