Direct neutrino-mass measurement achieves new, sub-electronvolt sensitivity - EurekAlert

The international KArlsruhe TRItium Neutrino (KATRIN) experiment in Germany recently reported a new upper limit on the mass of the neutrino. This limit—0.8 electronvolts (eV)—is the lowerst scientists have achieved. As the results are confirmed and refined, t…

The Science Neutrinos are the most abundant particles that have mass in the universe, but that mass is so small that scientists have not been able to measure it. To obtain that measurement, an inter… [+3224 chars]
