High Scale Mixing Unification and Large Neutrino Mixing Angles
Starting with the hypothesis that quark and lepton mixings are identical at or near the GUT scale, we show that the large solar and atmospheric neutrino mixing angles together with the small reactor angle Ue3 can be understood purely as a result of renormalization group evolution provided the three neutrinos are quasi-degenerate and have same CP parity. It predicts the common Majorana mass for ...
متن کاملBilarge neutrino mixing from supersymmetry with high-scale nonrenormalizable interactions
We suggest a supersymmetric (SUSY) explanation of neutrino masses and mixing, where nonrenormalizable interactions in the hidden sector generate lepton number violating Majorana mass terms for both right-chiral sneutrinos and neutrinos. It is found necessary to start with a superpotential including an array of gauge singlet chiral superfields. This leads to nondiagonal ∆L = 2 mass terms and alm...
متن کاملLarge Neutrino Mixing in Grand Unified Theories
A non-minimal, semi-realistic version of supersymmetric SU(5) grand unified theory is discussed. The solution of the doublet-triplet splitting problem leads to a better agreement between the predicted and observed values of the low-energy strong coupling constant and to a prolongation of the proton lifetime. A U(1) flavor symmetry allows to accommodate a realistic mass spectrum in the charged a...
متن کاملLarge Neutrino Mixing from Renormalization Group Evolution
The renormalization group evolution equation for two neutrino mixing is known to exhibit nontrivial fixed point structure corresponding to maximal mixing at the weak scale. The presence of the fixed point provides a natural explanation of the observed maximal mixing of νμ − ντ if the νμ and ντ are [email protected] [email protected] [email protected] [email protected]...
متن کاملLarge Neutrino Mixing Angles in Unified Theories
Typically in unified theories the neutrino mixing angles, like the Cabibbo-Kobayashi-Maskawa (CKM) angles of the quarks, are related to the small mass ratios between fermions of different generations and are therefore quite small. A new approach for explaining the intergen-erational mass hierarchies is proposed here which, while giving small CKM angles, naturally leads to neutrino angles of ord...
