Description

Abstract:

The KArlsruhe TRItium Neutrino experiment (KATRIN) is searching for the minute imprint of the neutrino mass in the endpoint region of the tritium beta-decay spectrum. KATRIN employs a high-intensity gaseous molecular tritium source and a high-resolution electrostatic filter with magnetic adiabatic collimation. The design neutrino-mass sensitivity is 0.2 eV/c2 after five years of data-taking.

The presentation we will focus on the lastet results of KATRIN. With the first and second data taking campaigns in 2019, for first time in the history of direct neutrino mass experiments, a sub-eV neutrino mass sensitivity could be reached. Moreover, complementary searches for light sterile neutrinos were performed based on these data sets. Besides these recent results, the talk will present future perspectives of KATRIN to search for physics beyond the Standard Model with an extended detector system, called TRISTAN.
