Evidence Against the Sciama Model of Radiative Decay of Massive Neutrinos
نویسندگان
چکیده
We report on spectral observations of the night sky in the band around 900 Å where the emission line in the Sciama model of radiatively decaying massive neutrinos would be present. The data were obtained with a high resolution, high sensitivity spectrometer flown on the Spanish MINISAT satellite. The observed emission is far less intense than that expected in the Sciama model. Subject headings: cosmology: diffuse radiation — elementary particles — ultraviolet: general

متن کاملDecaying Neutrinos and the Flattening of the Galactic Halo
The recently constructed Dehnen-Binney set of mass models for the Galaxy is used to show that the decaying neutrino theory for the ionisation of the interstellar medium (Sciama 1990a, 1993) requires the neutrino halo of the Galaxy to be as flattened as is observationally permitted (axial ratio q = 0.2 or shape E8). The argument involves an evaluation of the contribution of red-shifted decay pho...
متن کاملElectromagnetic Catalysis of a Neutrino Radiative decay or One More Source of Information on the Lepton Mixing Angles?
The radiative decay of ultrarelativistic massive neutrino νi → νjγ is investigated in electromagnetic fields in the framework of the Standard Model with lepton mixing. Estimates of the decay probability and “decay cross-section” for accelerator neutrinos of high energies in the electric field of nucleus permit one to discuss the general possibility of carrying out the neutrino experiment. Such ...
متن کاملEvidence for Neutrino Mass: a Decade of Discovery
Neutrino mass and mixing are amongst the major discoveries of recent years. From the observation of flavor change in solar and atmospheric neutrino experiments to the measurements of neutrino mixing with terrestrial neutrinos, recent experiments have provided consistent and compelling evidence for the mixing of massive neutrinos. The discoveries at Super-Kamiokande, SNO, and KamLAND have solved...

The radiative decay νH → νL+γ of massive neutrinos is analyzed in the framework of the standard model with lepton mixing for very strong magnetic fields B ≫ Bcr = me/e ∼ 4.14 × 10 G. The analysis is based on the approximate decay amplitude obtained by Gvozdev et al. Numerical results as well as analytical approximations for the decay rate are obtained for energies of the initial neutrino below ...
