Determination of neutrino masses, present and future

Abstract

Oscillation experiments show that neutrinos have masses. They however only determine the neutrinop mass differences. Information on the absolute masses can be obtained by studying the kinematics in weak decays, or by searching for neutrinoless double beta decay. Recent results are reviewed, as well as future projects.
