The analysis utilized approximately 36 million electron events collected between 2019 and 2021.

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

KATRIN: Neutrinos are lighter than 0.8 electronvolts - sfb1258 Significance for Physics KATRIN: Neutrinos are lighter than

The 2021 data confirmed that neutrinos are at least one million times lighter than electrons. this measurement is direct and model-independent

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

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

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.
