Charge breaking bounds in the Zee model
We study the possibility that charge breaking minima occur in the Zee model. We reach very different conclusions from those attained in simpler, two Higgs doublet models, and the reason for this is traced back to the existence of cubic terms in the potential. A scan of the Zee model’s parameter space shows that CB is restricted to a narrow region of values of the parameters.
متن کاملThe LSND Experiment and the Zee Model
A recent experiment LSND at Los Alamos has provided[1] an indication of ν µ − ν e oscillations with ∆m 2 of order 1ev 2 or greater and sin 2 2θ eµ between 2 × 10 −3 and 10 2. Such a value of ∆m 2 for ν µ − ν e oscillations was not expected in the standard seesaw model[2] suggested by SO(10) with a large mass hierarchy because it leads to too large a value of m(ν τ) to fit cosmological constrain...
متن کاملNew Trends in the Zee Model
Recent trends in the Zee model are reviewed. Especially, the importance of a serious constraint in the Zee model, sin 2θsolar = 1.0, is pointed out.
متن کاملCan the Zee Model Explain the Observed Neutrino Data?
The eigenvalues and mixing angles in the Zee model are investigated parameterindependently. When we require |∆m12/∆m23| 1 in order to understand the solar and atmospheric data simultaneously, the only solution is one which gives bi-maximal mixing. It is pointed out that the present best-fit value of sin 2θsolar in the MSW LMA solution cannot be explained within the framework of the Zee model, b...
متن کاملIs Zee Model The Model of Neutrino Masses?
Zee model leads naturally to two heavy, strongly degenerate and almost maximally mixed neutrinos and to one light neutrino with small mixing. This pattern coincides with the one needed for a solution of the atmospheric neutrino problem by νμ → ντ oscillations and for existence of the two component hot dark matter in the Universe. Furthermore, the oscillations νμ → νe can be in the range of sens...
