Abstract:
By combining experimental constraints from atmospheric and solar neutrino oscillations and the tritium beta decay endpoint, we infer upper limits of 4.4 eV on the and masses, if the universe consists of three neutrinos. For hierarchical mass spectra or we infer that m_{\nu_\alpha} \lsim 0.08 eV for . In a four neutrino universe, and assuming neutrino oscillations also account for the LSND experimental results, m_{\nu_\alpha} \lsim 5.4 eV. We also obtain lower limits on the masses.Note:
