First neutrino mass results from KATRIN

25.09.2019 11:15 – 12:15

The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to directly probe the neutrino mass with a sensitivity of 0.2 eV (90% CL).
KATRIN persues a model-independent approach, solely based on the kinematics of tritium beta decay. A non-zero neutrino mass manifests itself as a small spectral distortion close to the endpoint of the decay. In spring 2019 KATRIN performed its first neutrino mass measurement campaign. With this first data set new limits on the neutrino mass could be established, reaching for the first time the sub-eV regime. In this talk the KATRIN working principle and the first neutrino mass results will be presented. A short perspective to the future scientific program of KATRIN will be given.
