Scotogenesis in hybrid textures of neutrino mass matrix and neutrinoless double beta decay

We study the connection between dark matter (DM) and neutrinoless double beta (0νββ) decay in a scotogenic model with hybrid texture in the neutrino mass matrix. Characteristically, the framework allows to write all the non-zero elements of the mass matrix proportional to effective Majorana mass |Me...
