Deviations from Tri-Bimaximality and Quark-Lepton Complementarity

Understand

We study deviations from tri-bimaximality (TBM) and quark-lepton complementarity (QLC) in a model independent way.

• The current neutrino experimental data is well approximated by tri-bimaximal generation mixing but the QLC relations are not satisfied with each data of 1$\sigma$ level.
• This means that there exist deviations from the complementarity.
• The same fact for the TBM might be checked in the future neutrino experiments.
