New KATRIN results
Neutrinos weigh less than 0.45 electronvolts/c2 – precision scale KATRIN sets new record
The international KArlsruhe TRItium Neutrino Experiment (KATRIN) at the Karlsruhe Institute of Technology (KIT) has once again surpassed its own achievements. The latest data, recently published in Science, establish an upper limit of 8 x 10-37 kg (or in scientific language 0.45 eV/c2) for the neutrino mass. With this result, KATRIN, which measures neutrino mass in the laboratory using a model-independent method, has once again set a world record.
The publication at the SCIENCE Magazine appeared on 10th April 2025.
Here, the leading authors Alexey Lokhov (KIT) and Christoph Wiesinger (MPIK Heidelberg) explain the results (Youtube-video).
