Scientists Meet Scientists – TUM-IAS Wednesday Coffee Talk by Dr. Thierry Lasserre: “Latest results from KATRIN on neutrino mass and the search for sterile and relic neutrinos"
Events, WCT |
On June 22, 2022, Dr. Thierry Lasserre (French Alternative Energies and Atomic Commission/CEA; Alumnus IAS Hans Fischer Senior Fellow) will talk about “Latest results from KATRIN on neutrino mass and the search for sterile and relic neutrinos.”
Abstract:
I will report on the latest results from the Karlsruhe Tritium Neutrino Experiment (KATRIN). KATRIN probes the effective mass of electron anti-neutrinos via a high-precision measurement of the β-decay spectrum of tritium near its endpoint at 18.6 keV. In the first two campaigns taken in 2019, KATRIN has established that the effective mass of neutrinos is less than 0.8 eV/c2 (90% CL), setting a limit in the sub-eV range for the first time. I will also briefly show the search for light sterile neutrinos by KATRIN as well as the first results on the search for relic neutrinos produced about one second after the big bang.
