Radiative seesaw dark matter

چکیده
The singlet majoron model of seesaw neutrino mass is appended by one dark Majorana fermion $\chi$ with $L=2$ and complex scalar $\zeta$ $L=1$. This simple setup allows to obtain a small radiative anchored the same heavy right-handed neutrinos, whereas one-loop decay standard-model Higgs boson $\chi \chi + \bar{\chi} \bar{\chi}$ provides freeze-in mechanism for be light matter Universe.

Multicomponent Dark Matter in Radiative Seesaw Models
We discuss radiative seesaw models, in which an exact Z2 × Z′ 2 symmetry is imposed. Due to the exact Z2 × Z′ 2 symmetry, neutrino masses are generated at a two-loop level and at least two extra stable electrically neutral particles are predicted. We consider two models: one has a multi-component dark matter system and the other one has a dark radiation in addition to a dark matter. In the mult...
متن کاملVerifiable 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 کاملMinimal dark matter in type III seesaw
We explore the possibility of a new dark matter candidate in the supersymmetric type III seesaw mechanism where a neutral scalar component of the Y= 0 triplet can be the lightest supersymmetric particle. Its thermal abundance can be in the right range if non-standard cosmology such as kination domination is assumed. The enhanced cross-section of the dark matter annihilation to WW can leave dete...

متن کاملSeesaw theories at LHC and warm dark matter
Explaining the origin of neutrino masses clearly requires new physics beyond the Standard Model. I focus on the Seesaw paradigm and discuss a few simplest extensions of the SM that give Majorana masses to the active neutrinos. If realized at TeV scale, seesaw theories could manifest themselves in lepton number violating signatures at both low-energy processes and high-energy collider experiment...
