In the light of the recent Super-Kamiokande experiments which demonstrate neutrino oscillation, and therefore a non zero mass, it is pointed out how such a mass has also been deduced theoretically.
We briefly review the recent activity on neutrino masses and mixings which was prompted by the confirmation of neutrino oscillations by the Superkamiokande experiment.
We examine how constraints can be placed on the neutrino component of dark matter by an accurate measurement of neutrinoless double beta ($0\nu\beta\beta$) decay and the solar oscillation amplitude. We comment on the alleged evidence for…

A phenomenological neutrino mass matrix is proposed to explain the solar and atmospheric neutrino deficits and to present the neutrino as a candidate of hot dark matter in the $3\nu_L+3\nu_R$ framework. The realization of mixing angles…
We quantify the extent to which future experiments will test the existence of neutrinoless double-beta decay mediated by light neutrinos with inverted-ordered masses. While it remains difficult to compare measurements performed with…
