Description

KATRIN is probing the effective electron anti-neutrino mass by a precise measurement of the tritium beta-decay spectrum near its kinematic endpoint. Based on the first two measurement campaigns a world-leading upper limit of 0.8 eV (90% CL) was placed. New operational conditions for an improved signal-to-background ratio, the steady reduction of systematic uncertainties and a substantial increase in statistics allow us to expand this reach. In this talk, I will present the status of the KATRIN experiment and provide an insight into the latest result.
