Abstract

We have discussed predictions of Ue3|U_{e3}| and JCPJ_{CP} in the framework of the neutrino mass matrix with two zeros. In the case of the best fit values of tan2θ12\tan^2\theta_{12}, tan2θ23\tan^2\theta_{23}, Δmsun2\Delta m^2_{\rm sun} and Δmatm2\Delta m_{\rm atm}^2, the prediction of Ue3|U_{e3}| is 0.110.140.11\sim 0.14. The lower bound of Ue3|U_{e3}| is 0.05, which depends on tanθ12\tan\theta_{12} and tanθ23\tan\theta_{23}. We have investigated the stability of these predictions taking account of small corrections to zeros, which may come from radiative corrections or off-diagonal elements of the charged lepton massmatrix. The lower bound of Ue3|U_{e3}| comes down considerably due to the small corrections to zeros.
