Neutrino Phenomenology from Democratic Approach

In this article, we derive the tiny neutrino masses and mixings from the democratic and diagonal texture approach, which consistent with the recent experimental oscillation data. The unitary rotation matrices, which diagonalize the neutrino mass matrices are obtained by a specific parametrization of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) mixing matrix. From which, we tried to calculate all three mixing angles as well as the Dirac CP-violating phase interms of model mixing parameters. In particular, the deviation from the tribimaximal mixing is explained in this model. Along with the Jarlskog parameter in terms of model parameter and neutrino-less double beta decay (NDBD) has been discussed briefly.Comment: Minor corrections in model; title and abstract changed accordingl
