Verifiable radiative seesaw mechanism of neutrino mass and dark matter

Neutrino oscillations have established that neutrinos nu_i have very small masses. Theoretically, they are believed to arise through the famous seesaw mechanism from their very heavy and unobservable Dirac mass partners N_i. It is proposed here in a new minimal extension of the standard model with a second scalar doublet (eta⁺, eta⁰) that the seesaw mechanism is actually radiative, and that N_i and (eta⁺, eta⁰) 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.
