Two Sterile Neutrinos as a Consequence of Matter Structure *
نویسنده
چکیده
An algebraic argument based on a series of generalized Dirac equations, truncated by an ”intrinsic Pauli principle”, shows that there should exist two sterile neutrinos as well as three families of leptons and quarks. Then, the influence of these additional neutrinos on neutrino oscillations is studied. As an example, a specific model of effective five–neutrino texture is proposed, where only the nearest neighbours in the sequence of five neutrinos ordered as νs , ν ′ s , νe , νμ , ντ are coupled through the 5 × 5 mass matrix. Its diagonal elements are taken as negligible in comparison with its nonzero off–diagonal entries. PACS numbers: 12.15.Ff , 14.60.Pq , 12.15.Hh .

A ménage à trois of eV-scale sterile neutrinos, cosmology, and structure formation
We show that sterile neutrinos with masses & 1 eV, as motivated by several short-baseline oscillation anomalies, can be consistent with cosmological constraints if they are charged under a hidden sector force mediated by a light boson. In this case, sterile neutrinos experience a large thermal potential that suppresses mixing between active and sterile neutrinos in the early Universe, even if v...
متن کاملNaturally Light Sterile Neutrinos in Gauge Mediated Supersymmetry Breaking
Moduli are generic in string (M) theory. In a large class of gauge-mediated Supersymmetry breaking models, the fermionic components of such fields have very light masses, around the eV scale, and non-negligible mixing with active neutrinos, of order 10. Consequently, these fermions could play the role of sterile neutrinos to which active neutrinos oscillate, thus affecting measurements of solar...
متن کاملComment on “A New Dark Matter Candidate: Non–thermal Sterile Neutrinos”
I point out that the sterile neutrinos suggested as candidates for “cool” Dark Matter will decay through their mixing with light neutrinos. This leads to an upper bound of about 200 keV on the mass of the sterile neutrinos, but might facilitate their detection. Recently Shi and Fuller proposed [1] a new kind of Dark Matter candidate: a sterile neutrino, with small but non–vanishing mixing with ...
متن کاملSterile neutrinos as the origin of dark and baryonic matter.
We demonstrate for the first time that three sterile neutrinos alone can simultaneously explain neutrino oscillations, the observed dark matter, and the baryon asymmetry of the Universe without new physics above the Fermi scale. The key new point of our analysis is leptogenesis after sphaleron freeze-out, which leads to resonant dark matter production, evading thus the constraints on sterile ne...
متن کاملSterile Neutrinos in the Milky Way: Observational Constraints
We consider the possibility of constraining decaying dark matter by looking out through the Milky Way halo. Specifically we use Chandra blank sky observations to constrain the parameter space of sterile neutrinos. We find that a broad band in parameter space is still open, leaving the sterile neutrino as an excellent dark matter candidate. Subject headings: dark matter — elementary particles — ...
