Massive neutrinos and cosmology
Abstract
Description
Cosmology can provide information on the absolute scale of neutrino masses, complementary to the results of tritium beta decay and neutrinoless double beta decay experiments. We show how the analysis of data from the anisotropies of the cosmic microwave background radiation and from the distribution of cosmological large-scale structure, combined with other experimental results, provides an upper bound on the sum of neutrino masses. We also discuss the sensitivity of future cosmological data to neutrino masses.
