Neutrino Mass and the KATRIN Experiment
Recently, the Karlsruhe Tritium Neutrino Experiment (KATRIN) set a new upper limit on the combined mass of all three known neutrino types — no more than 8.8 x 10⁻⁷ times the mass of an electron, doubling the precision of past estimates.
- Neutrinos are elusive subatomic particles that interact so weakly with matter that they can travel through a light-year’s worth of metal virtually undisturbed, making them incredibly hard to detect.
- KATRIN observes tritium decay and measures the energy of emitted electrons — indirectly revealing the neutrino mass.
- Unlike cosmological models or neutrinoless double beta decay experiments, KATRIN’s result is ....
