Bimaximal neutrino mixing and neutrino mass matrix
Bimaximal neutrino mixing and neutrino mass matrix
We show that the bimaximal neutrino mixing pattern suggested by solar and atmospheric neutrino data can be derived from the maximal, symmetric, four-neutrino mixing in the limit that one of the neutrinos is made heavy. Imposing the constraints of no neutrinoless double beta decay and a 20% hot dark matter …
