The masses of the neutrinos

Abstract

If the cosmological limits on the sum of the neutrino masses are taken seriously we have first measurements of the masses of the neutrinos. Using the Planck experiment's limit ${\sum }_{i=1}^3{m}_i<230meV$ and some simple assumptions on measurement uncertainties the mass of the heaviest neutrino is $63\pm 11meV$ and the lightest $40\pm 18meV$ for either hierarchy.
