Ks. Kang et al., A SIMPLE MODIFICATION OF THE MAXIMAL MIXING SCENARIO FOR 3 LIGHT NEUTRINOS, Zeitschrift fur Physik. C, Particles and fields, 72(4), 1996, pp. 671-675
We suggest a simple modification of the maximal mixing scenario (with
Sg permutation symmetry) for three light neutrinos. Our neutrino mass
matrix has smaller permutation symmetry S-2(nu(mu) reversible arrow nu
(e)), and is consistent with all neutrino experiments except the Cl-37
experiment. The resulting mass eigenvalues for three neutrinos are m(
1) approximate to (2.55 - 1.27) x 10(-3) eV, m(2,3) approximate to (0.
71 - 1.43) eV for Delta m(LSND)(2) = 0.5 - 2.0 eV(2). Then these light
neutrinos can account for similar to (2.4 - 4.8)% (6.2 - 12.4%) of th
e dark matter for h = 0.8 (0.5). Our model predicts the nu(mu) --> nu(
tau) oscillation probability in the range sensitive to the future expe
riments such as CHORUS and NOMAD.
