Determination of the absolute electron (anti)-neutrino mass

The mass scale of neutrinos is one of the fundamental open questions in modern physics, with far-reaching implications from cosmology to particle physics. Precision measurements of the kinematics of weak interactions, notably of the H-3 β-decay spectrum and the Ho-163 electron capture spectrum, represent the only model independent approach to address this question in a laboratory experiment.The next milestone is to reach sub-eV sensitivity with respect to the electron (anti-)neutrino mass. This goal can only be achieved by bringing together
expertise from different fields such as nuclear and particle physics, atomic and molecular physics, theory and phenomenology.
The objective of this workshop is to foster the discussion between theorists and experimentalists involved in the different projects at a time when large experiments are approaching the starting phase. Looking further ahead, the workshop will also address prospects of extending the physics reach of current and next-generation experiments beyond the quest for neutrino masses by probing for the existence of light and medium-mass sterile neutrinos, searching for Lorentz invariance violation, or attempting detection of relic neutrinos.
