Nonzero $θ_{13}$ and Neutrino Masses from the Modified Tribimaximal
Neutrino Mixing Matrix    [PDF]

Experimental evidence of nonzero and relatively large $\theta_{13}$ have been reported by some collaborations. In order to accommodate the nonzero and relatively large $\theta_{13}$, we modified the tribimaximal mixing matrix by introducing a simple perturbation matrix into tribimaximal neutrino mixing matrix. In this scenario, we obtained 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 tribimaximal mixing matrix, we then have the neutrino mass spectrum in normal hierarchy. Some phenomenological implications are also discussed.
