An Asymmetric TBM Texture

We construct a texture where the Seesaw matrix is diagonalized by the TriBiMaximal (TBM) matrix with a phase. All CKM and PMNS angles are within their pdg values, and the mass relations of quarks and charged leptons extrapolated to GUT scale are satisfied, including the Gatto relation. The novel ingredient is the asymmetry of the down-quark and charged lepton Yukawa matrices. Explaining the reactor angle requires a $\require{cancel} \cancel {CP}$phaseintheTBMmatrix,resultingintheJarlskog-Greenberginvariantat$|J|=0.028$,albeitwithanundeterminedsign\mathrm{.}While$SO(10)$ restrains the right-handed neutrino Majorana matrix, the neutrino masses are left undetermined.
