KATRIN Experiment Tightens Neutrino Mass Limit to 0.45 eV

About 100 researchers, attached to the Katrin scale in Germany, have just published in the journal "Science" their latest estimate of the mass of the lightest particles.

Ghost Particles Just Got Lighter: KATRIN Sets a New Benchmark for Neutrino Mass

Neutrinos, the mysterious and nearly massless particles that barely interact with anything, are revealing new secrets through the KATRIN experiment. Using tritium decay and advanced spectrometry, KATRIN has slashed the upper limit on neutrino mass, pushing our understanding of fundamental physics into new territory. With 250 days of data already analyzed and more to come, [...]

Neutrino Mass Mystery Shrinks with Latest KATRIN Results

In just the first 259 days of data collection, KATRIN, a beta-decay-based detector in Germany, has set the smallest upper limit yet on the mass of the neutrino—the universe’s lightest massive particle

Neutrino mass: most precise measurement shows they are a million times smaller than electrons

Physicists in Germany have performed the most accurate measurement of the mass of the fundamental particle neutrinos.

Neutrinos Have No Business Being This Freaking Small

A new measurement finds the universe's teensiest particles weigh no more than one-millionth the mass of an electron.

Elusive neutrinos' mass just got halved — and it could mean physicists are close to solving a major cosmic mystery

Physicists have set a new upper limit on the mass of neutrinos. And the finding could poke a big hole in the Standard Model of particle physics.
