Scientists observe the tritium beta decay process, where a tritium nucleus decays into helium, an electron, and an antineutrino.

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

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

Below is a draft "paper" summarizing the key findings and significance of the KATRIN experiment as of mid-2021, which would have been the focus of recordings from that date.

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) Scientists observe the tritium beta decay process, where
