The KATRIN experiment has turned up a new, more-precise-than-ever measurement for the barely-detectable neutrino mass. ... (KATRIN), have no more than 0.0002% the mass of an electron.

Silver-110’s decay reveals a promising path to measure antineutrino mass. New data could reshape future neutrino studies.

The experiment measures the mass of an electron by analyzing the relationship between the magnetic field, the electric potential, and the radius of the electron's circular path.

The invisible dark matter is one of the universe's biggest mysteries, and its existence is confirmed only by the ...

An experiment nearly two decades in the making has finally unveiled its measurements of the mass of the universe’s most abundant matter particle: the neutrino. The neutrino could be the weirdest ...

With the current data from the KATRIN experiment, an upper limit of 0.45 electron volt/c 2 (corresponding to 8 x 10-37 kilograms) could be derived for the neutrino mass.

Now that's precision measurement: the electron is a perfect sphere, give or take barely one part in a million billion. The result comes from the latest in a long line of experiments to probe the ...

The KATRIN experiment suggests that the tiny subatomic particles have masses a minuscule fraction of an electron’s. ... Neutrinos must have a mass of 1.1 electron volts or less, ...

Although it is extremely unlikely to happen in any one nucleus, such a decay should be seen over the lifetime of the CUORE experiment – which will consist of 1000 cubes of tellurium oxide, each ...

In the mid-2000s the Mainz Neutrino Mass Experiment in Germany had set the upper limit of a neutrino’s mass at 2.3 electron volts. And in early 2022 data from the Karlsruhe Tritium Neutrino ...

Researchers have directly observed high-energy electron and muon neutrino interactions for the first time in the teraelectronvolt (TeV) energy range. This landmark moment was achieved at CERN’s ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy's Thomas Jefferson ...
