Abstract
Present experimental data from neutrino oscillations have provided much information about the neutrino mixing angles. Since neutrino oscillations only determine the mass squared differences Δmij2. = mi2 - mj2, the absolute values for neutrino masses mi can not be determined using data just from oscillations. In this work we study implications on neutrino masses from a geometric mean mass relation m2 = √m1m 3which enables one to determined the absolute masses of the neutrinos. We find that the central values of the three neutrino masses and their 2σ errors to be m1 = (1.58 ± 0.18)meV, m 2 = (9.04±0.42)meV, and m3 = (51.8±3.5)meV. Implications for cosmological observation, beta decay and neutrinoless double beta decays are discussed. © World Scientific Publishing Company.
