Quark lepton complementarity with lepton and quark mixing data predict θ13 PMNS=(9+1 -2)°
Abstract
The complementarity between the quark and lepton mixing matrices is shown to provide a robust prediction for the neutrino mixing angle θ13 PMNS. We obtain this prediction by first showing that the matrix VM, product of the CKM and PMNS mixing matrices, may have a zero (1,3) entry, which is favored by the experimental data. Hence models with bimaximal or tribimaximal forms of the correlation matrix VM are quite possible. Any theoretical model with a vanishing (1,3) entry of VM, which is in agreement with the quark data, and the solar and the atmospheric mixing angle leads to θ13 PMNS=(9+1 -2)°. This value is consistent with the present 90% CL experimental upper limit.
