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

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

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.

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.

Researchers from the KATRIN (Karlsruhe Tritium Neutrino) experiment report the most precise measurement of the upper mass limit of the neutrino to date, establishing it as 0.45 electron volts (eV ...

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 ...

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 ...

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 ...

A new experiment pulled off the most precise measurement of an electron’s self-generated magnetic field—and the ... the electron’s lighter mass makes it 40,000 times harder to search for ...

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 ...
