Workshop objectives
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 3H β-decay spectrum and the 163Ho 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 the workshop series Determination of the absolute electron (anti)-neutrino mass (short NuMass) 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. Workshops 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.
Past issues
The Trento Era - the first three years
The first three issues took place at the European Center for Theoretical Studies in Nuclear Physics and Related Areas (ECT*) in Trento, Alto Adige, Italy and were initially organized by Kathrin Valerius (KATRIN, KIT) and Loredana Gastaldo (ECHo, U Heidelberg).

The Post-Trento Era - expanding the capacity
ECT* in Trento was a beautiful and inspiring location, but it had one crucial limitation: its restricted capacity for participants. During this period, all collaborations were growing significantly in both size and scope. For example, KATRIN was entering full data-taking, ECHo and HOLMES were obtaining their first data, and Project 8 had already published successful results from its early phases.
As a result, it became clear that a new venue was needed - one that could accommodate a larger number of participants while preserving the interactive workshop atmosphere. Consequently, it was decided that the organization of each workshop edition would rotate among different institutions. The established biennial schedule in spring has been maintained.
