Verifiable Radiative Seesaw Mechanism of Neutrino Mass and Dark Matter
A minimal extension of the Standard Model is proposed, where the observed lefthanded neutrinos obtain naturally small Majorana masses from a one-loop radiative seesaw mechanism. This model has two candidates (one bosonic and one fermionic) for the dark matter of the Universe. It has a very simple structure and should be verifiable in forthcoming experiments at the Large Hadron Collider. In the ...
متن کاملNeutrino Mass and Dark Matter
Despite direct observations favoring a low mass density, a critical density universe with a neutrino component of dark matter provides the best existing model to explain the observed structure of the universe over more than three orders of magnitude in distance scale. In principle this hot dark matter could consist of one, two, or three species of active neutrinos. If all present indications fo...
متن کاملSinglet fermion dark matter and electroweak baryogenesis with radiative neutrino mass
The model of radiative neutrino mass with dark matter proposed by one of us is extended to include a real singlet scalar field. There are then two important new consequences. One is the realistic possibility of having the lightest neutral singlet fermion (instead of the lightest neutral component of the dark scalar doublet) as the dark matter of the Universe. The other is a modification of the ...
متن کاملNeutrino Mass, Dark Matter, and Leptogenesis
It is proposed that dark matter is the origin of neutrino mass, thereby linking inexorably two undisputed (and seemingly unrelated) pieces of evidence for physics beyond the Standard Model. Leptogenesis at the TeV scale may also be possible, as well as a measurable contribution to the muon anomalous magnetic moment. Talk at NOW2006, Conca Specchiulla, Otranto, Italy.
متن کاملNeutrino Mass, Dark Matter and Inflation
We show that spontaneous breaking of global B − L symmetry responsible for small neutrino masses via the seesaw mechanism provides a unified picture of hybrid inflation and dark matter if the scale of B − L breaking is close to the GUT scale. The majoron which acquires a small mass in the milli-eV range due to Planck scale breaking of B − L is the dark matter candidate. The coupling of the majo...
