Description

Light sterile neutrinos with a mass on the eV-scale could explain several anomalies observed in short-baseline oscillation experiments. The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to directly determine the effective electron anti-neutrino mass by measuring the tritium beta decay spectrum. The measured spectrum can also be investigated for the signature of light sterile neutrinos.
With this poster we present the result of the light sterile neutrino analysis of the first five KATRIN measurement campaigns. To handle the computational challenge, a neural network is used. The obtained result is compared to results from other experiments and anomalies in the field of light sterile neutrinos.
