Recent Neutrino Data and a Realistic Tribimaximal-like Neutrino Mixing Matrix

Understand

In light of the recent neutrino experimental results from Daya Bay and RENO Collaborations, we construct a realistic tribimaximal-like Pontecorvo-Maki-Nakagawa-Sakata (PMNS) leptonic mixing matrix.

• Motivated by the Qin-Ma (QM) parametrization for the quark mixing matrix in which the CP-odd phase is approximately maximal, we propose a simple ansatz for the charged lepton mixing matrix, namely, it has the QM-like parametrization, and assume the tribimaximal mixing (TBM) pattern for the neutrino mixing matrix.
• The deviation of the leptonic mixing matrix from the TBM one is then systematically studied.
• While the deviation of the solar and atmospheric neutrino mixing angles from the corresponding TBM values, i.e.
