Quasi-Degenerate Neutrino Masses in Terms of Mass-Squared Differences
arXiv:hep-ph/0304207 · doi:10.1016/j.physletb.2003.06.052
Abstract
The absolute neutrino masses are obtained in terms of the atmospheric and solar mass-squared differences within the framework of low energy phenomenology by suggestion of a quantitative analogy between the hierarchies of the neutrino and charged lepton mass ratios. It points to a quasi-degenerate three neutrino mass pattern with the neutrino mass scale likely located in the range 0.1 -- 0.3 eV, and best-fit value m = 0.18 -- 0.20 eV. Restrictions on the neutrino mass scale from the WMAP data are considered. Possible indirect evidence in favor of quasi-degenerate neutrino masses is noted.
