KATRIN analysis with the covariance matrix approach — •Lisa Schlüter for the KATRIN collaboration — MPP München
The KArlsruhe TRItium Neutrino (KATRIN) experiment is designed to determine the effective mass of the electron-antineutrino with an sensitivity of 200 meV/c2 (90% C.L.) in a direct and model-independent way. The neutrino mass can be inferred from the shape of the endpoint region of the tritium β-decay spectrum, which is measured using a MAC-E filter and a Windowless Gaseous Tritium Source (WGTS). This talk presents an analysis of the KATRIN Tritium commissioning measurements, including systematic effects based on the covariance matrix approach, using the Samak simulation analysis package.
