Hot Dark Matter

Scientific paper

Hot dark matter, now ignored, could have had an appreciable effect on structure formation, even as a minor component. If the LSND results are correct, then in the 2+2 neutrino scheme the total neutrino mass would be about 1-2 eV (3-6% of critical mass), or even as much as 5 eV. That scheme, which requires a light sterile neutrino, has been discounted recently, but this view is based on incorrect assumptions. That there are only the three light active neutrinos is popular because of some success in fitting solar neutrino data. This may also be incorrect, since Cl and Ga solar neutrino data yield statistically compelling evidence for rotational modulations of the neutrino flux, indicating that Resonant-Spin-Flavor-Precession could be the process responsible. To that evidence, summarized here, is now added that from recently released Super-Kamiokande data.
