Titre |
First neutrino mass results from KATRIN |
|
Résumé |
The KATRIN experiment is designed to directly probe the mass of neutrinos with a
sensitivity of 0.2 eV (90% CL). KATRIN offers a model-independent approach based
principally 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 electron spectrum. In spring
2019 KATRIN carried out its first neutrino mass measurement campaign. This first dataset
established new limits on neutrino mass reaching for the first time the sub-eV regime. In
this presentation the operating principle of KATRIN and the first neutrino mass results will
be presented. |
