Latest Results from the KATRIN Experiment
Time: 2:00 pm - 3:00 pm
Place: virtual:
Speaker: Christian Karl, Max Planck Institute for Physics and Technical University of Munich
Abstract: From neutrino oscillation experiments we know that at least two neutrino mass eigenstates have a non-zero rest-mass. However, the absolute scale of the neutrino mass cannot be assesed from the oscillation. One approach to infer the mass scale is to measure the electron energy spectrum of beta-decay precisely in the so-called endpoint region where the electron takes most of the surplus energy. The currently leading experiment in this field is the Karlsruhe Tritium Neutrino (KATRIN) experiment. It is designed to measure the effective electron anti-neutrino mass (m_nu) with a sensitivity of 200 meV at 90% confidence level. In this talk we give an overview of the experimental setup, measurement principle and data analysis of KATRIN and discuss the latest results which limit (m_nu) to less than 0.8 eV (90% C.L.). Finally, we take a look at the possibilities with further measurement campaigns and show some recent advancements in our data analysis.
