Implications of a class of neutrino mass matrices with texture zeros for non-zero
A class of neutrino mass matrices with texture zeros realizable using the
group within the framework of type (I+II) seesaw mechanism naturally
admits a non-zero and allows for deviations from maximal mixing.
The phenomenology of this model is reexamined in the light of recent hints for
non-zero .Comment: some references added, version published in Physical Review
Neutrino Parameter Space for a Vanishing Element in the Neutrino Mass Matrix
The consequences of a texture zero at the entry of neutrino mass matrix
in the flavor basis, which also implies a vanishing effective Majorana mass for
neutrinoless double beta decay, have been studied for Majorana neutrinos. The
neutrino parameter space under this condition has been constrained in the light
of all available neutrino data including the CHOOZ bound on .Comment: 10 pages, 4 eps figures, typographical errors corrected, version to
