Neutrino oscillation experiments and antisymmetric Yukawa Matrices

We propose a set of Yukawa textures for the Dirac and Majorana Yukawa mass matrices of the neutrinos. These set of textures have one parameter in the Majorana sector and no free parameters in the Dirac sector. We show that such textures can lead to a successful prediction for the squared mass differences relevant to solar, atmospheric and LSND neutrino oscillation experiments. Furthermore a pair of neutrinos remain in the 1 eV range to serve as a candidate of Hot dark matter. A crucial prediction of these textures is the light Majorana mass term of the left handed electron neutrino, testable by neutrinoless double beta decay experiments in near future.
