Scientists observe the tritium beta decay process, where a tritium nucleus decays into helium, an electron, and an antineutrino.
A giant 200-tonne spectrometer measures the energy of the emitted electrons. By analyzing the maximum energy (endpoint) of these electrons, the mass of the "missing" neutrino is inferred. 3. Key Findings (2021 Status) katrin [2021-07-09 18-28-07].mp4
🔬 Scientific Report: Direct Measurement of the Neutrino Mass Scientists observe the tritium beta decay process, where
The video filename katrin [2021-07-09 18-28-07].mp4 likely refers to a recording related to the (KArlsruhe TRItium Neutrino experiment) during its critical 2021 measurement phase. On July 9, 2021, a major scientific paper— "Language models enable zero-shot prediction of the effects of mutations" —was also released, though the experiment name "KATRIN" is most famously associated with breakthrough results in neutrino mass research published around that same time. The KATRIN experiment has successfully established a new
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
