| |
| <hidden TTP02-12 On the hierarchy of neutrino masses > We present a model of neutrino masses combining the seesaw mechanism and |
| strong Dirac mass hierarchy and at the same time exhibiting a significantly |
| reduced hierarchy at the level of active neutrino masses. The heavy Majorana |
| masses are assumed to be degenerate. The suppression of the hierarchy is due to |
| a symmetric and unitary operator R whose role is discussed. The model gives |
| realistic mixing and mass spectrum. The mixing of atmospheric neutrinos is |
| attributed to the charged lepton sector whereas the mixing of solar neutrinos |
| is due to the neutrino sector. Small U_e3 is a consequence of the model. The |
| masses of the active neutrinos are given by $\mu_3\approx\sqrt{\Delta m_{@}^2}$ |
| and $\mu_1/\mu_2\approx \tan^2\theta_\odot$. |
