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
