Neutrino mass curbs the formation of fine details of the cosmic web. These two computer simulations show the cosmic web with either massless neutrinos (left) or neutrinos with a summed mass of 500 ...
One of those experiments, Project 8, a long-term collaboration of international scientists including Yale researchers, just proved the viability of a new method to measure neutrino mass. Physicists ...

The Possible Mass Of The Neutrino Is Now Half What It Used To BeThe KATRIN collaboration improved on its previous result by a factor of two. According to the experiment, the effective electron neutrino mass cannot be more than 0.45 electron volts, which is ...
This helps them estimate the neutrino’s mass. The trick is, this has to be done with extreme accuracy. That’s why KATRIN includes one of the world’s most advanced spectrometers, ...
New data establish an upper limit of 0.45 eV/c2 (equivalent to 8 x 10-37 kilograms) for the neutrino mass. KATRIN measures neutrino mass in the laboratory using a model-independent method.
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 ...
The neutrino’s mass limits the maximum energy the electron can have. Using measurements of a whopping 36 million electrons, the researchers looked for that subtle effect of the antineutrino’s ...
The latest measurement pushes the possible mass of the neutrino lower than the previous limit set in 2022 by the KATRIN collaboration, of no more than 0.8 electronvolts.
In addition to the precise measurement of the neutrino mass, KATRIN is already planning the next phase. Starting in 2026, a new detector system, TRISTAN, will be installed.
Nearly a decade ago, a detector searching for ghostly cosmic particles found two anomalous signals in Antarctic ice. But ...
