abstract

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 $\require{cancel} \cancel {CP}$ phase in the TBM matrix, resulting in the Jarlskog-Greenberg invariant at $|J|=0.028$, albeit with an undetermined sign. While $SO(10)$ restrains the right-handed neutrino Majorana matrix, the neutrino masses are left undetermined.

    hep-ph 2019-08 conditional novelty 5.0 of 10

    In CPmu-tau symmetric seesaw models, flavoured leptogenesis works with M2/M1 as low as 4.7, lowering the old lower bound on M1 to about 7.5e9 GeV and allowing N2-dominated scenarios in roughly a quarter of the paramet...
