KATRIN: Neutrinos are lighter than 0.8 electronvolts - sfb1258

Unlike cosmological observations, this measurement is direct and model-independent , meaning it does not rely on assumptions about the early universe. 4. Significance for Physics katrin [2021-07-09 18-28-07].mp4

The KATRIN experiment has successfully established a new world record for the upper limit of the , breaking the "1 eV barrier" for the first time in a laboratory setting. Using the beta decay of tritium, the international collaboration has limited the neutrino mass to less than 0.8 electronvolts (eV) with unprecedented precision. 2. Experimental Methodology KATRIN: Neutrinos are lighter than 0

The measurement is conducted at the using a 70-meter-long beamline. this measurement is direct and model-independent

The 2021 data confirmed that neutrinos are at least one million times lighter than electrons.
