A natural scotogenic model for neutrino mass & dark matter
In this letter, we propose an extension of the scotogenic model where singlet Majorana particle can be dark matter (DM) without the need of a highly suppressed scalar coupling of the order O(10−10). For that, the SM is extended with three singlet Majorana fermions, an inert scalar doublet, and two (...
