Sterile neutrino in a minimal three-generation see-saw model
Biswajoy Brahmachari Sandhya Choubey Rabindra N Mohapatra
We investigate symmetries in Dirac and Majorana mass matrices of neutrinos in a three-generation scenario. We show that if we invoke

Neutrinoless double beta decay with small and hierarchical neutrino mass
We construct a model where neutrino Majorana masses are small and hierarchical but where neutrinoless double beta decay occurs at an observable rate potentially detectable by present day experiments.
