Abstract
Neutrino oscillations have established that neutrinos have very small masses. Theoretically, they are believed to arise through the famous seesaw mechanism from their very heavy and unobservable Dirac mass partners . It is proposed here in a new minimal extension of the standard model with a second scalar doublet (, ) that the seesaw mechanism is actually radiative, and that and (, ) are experimentally observable at the forthcoming Large Hadron Collider, with the bonus that the lightest of them is also an excellent candidate for the dark matter of the Universe.
