A simple motivated completion of the standard model below the Planck scale: Axions and right-handed neutrinos
We study a simple Standard Model (SM) extension, which includes three families of right-handed neutrinos with generic non-trivial flavor structure and an economic implementation of the invisible axion idea. We find that in some regions of the parameter space this model accounts for all experimentall...
