Determination of the absolute electron (anti)-neutrino mass

Determining the absolute neutrino mass scale would answer one of the most important questions in Physics. The KATRIN experiment, designed for the direct determination of the effective electron anti-neutrino mass, has recently released a new limit. New H-3 based experiments as Project8, PTOLEMY and Ho-163 based experiments ECHo and HOLMES are completing the R&D phase with publications of new data. The availability of high precision H-3 and Ho-163 spectra will offer the possibility to also search for signatures which could be attributed to beyond the Standard Model theories.
The objectives of this workshop are to offer a unique platform for theorists to discuss details of experiments, which are typically not emphasized, in order to gain a deeper understanding of released data and to provide indications to experimentalists on how experiments could be shaped for new searches. Our goal is to better exploit the potential of present and future experiments.
