Determination of the absolute electron (anti)-neutrino mass

The absolute neutrino mass scale could be the key for the theory beyond the Standard Model. Since the analysis of cosmological observations is approaching sensitivities close to the minimal allowed sum of neutrino masses and experiments searching for neutrinoless double beta decay are getting more sensitive, the quest for results from direct searches for the electron (anti-)neutrino mass by means of kinematic analysis is becoming very pressing. Presently two isotopes are in the spotlight: H-3 and Ho-163. KATRIN, Project 8 and PTOLEMY using H-3 and ECHo, HOLMES and NuMECS using Ho-163 aim to reach subeV sensitivity within the next few years.

The objective of this 2nd workshop is to foster the exchange between theorists and experimentalists in the light of new results achieved by experiments and to open a platform for discussions about future approaches to extend the sensitivity of kinematic measurements of the neutrino mass below 100 meV.
