We consider a class of gauged U(1) extensions of the Standard Model (SM), where the light neutrino masses are generated by an inverse seesaw mechanism. In addition to the three right handed neutrinos, we add three singlet ...

We study the minimal type-III seesaw model in which we extend the SM by adding two SU (2) L triplet fermions with zero hypercharge to explain the origin of the non-zero neutrino masses and mixing. We show that the naturalness ...

We analyze the effect of the Dark-large mixing angle (DLMA) solution on the effective Majorana mass (m??) governing neutrino-less double beta decay (0???) in the presence of a sterile neutrino. We consider the 3+1 picture, ...

We study the implications of the Dark-LMA (DLMA) solution to the solar neutrino problem for neutrinoless double beta decay (0???). We show that, while the predictions for the effective mass governing 0??? remain unchanged ...
