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
The analysis utilized approximately 36 million electron events collected between 2019 and 2021.
The measurement is conducted at the using a 70-meter-long beamline. katrin [2021-07-09 18-28-07].mp4
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 Experiment (Karlsruhe Institute of Technology) Date Reference: July 2021 Analysis Phase 1. Executive Summary The KATRIN experiment has successfully established a new
The 2021 data confirmed that neutrinos are at least one million times lighter than electrons.
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. this measurement is direct and model-independent
