Nonzero ${\theta }_{13}$ and Neutrino Masses from the Modified Tribimaximal Neutrino Mixing Matrix

Abstract

In order to accommodate nonzero and relatively large of mixing angle ${\theta }_{13}$, we modified the tribimaximal mixing(TBM) matrix by introducing a simple perturbation matrix to perturb TBM matrix. The modified TBM can reproduce nonzero mixing angle ${\theta }_{13}=7.9^0$ which is in agreement with the present experimental results. By imposing two zeros texture into the obtained neutrino mass matrix from modified TBM, we then have the neutrino mass spectrum in normal hierarchy. Some phenomenological implications are also discussed
