Abstract

We revisit the Fritzsch-type lepton mass matrix models confronted with new experiments for neutrino mixings. It is shown that the model is viable and leads to a rather narrow range of free parameters. Using empirical mixing information between νe\nu_e and νμ\nu_\mu, and between νμ\nu_\mu and ντ\nu_\tau, it is predicted that the mixing angle between nuenu_e and ντ\nu_\tau is in the range 0.04<U13<0.200.04<|U_{13}|<0.20, consistent with the CHOOZ experiment and the lightest neutrino mass is 0.0004<m1<0.00300.0004<m_1<0.0030 eV. The range of the effective mass measured in double beta decay is 0.002<<mee><0.0070.002<< m_{ee}><0.007 eV.
