Scientists are using “trapped ions” in highly precise experiments to search for a new, fifth force of nature that could help ...

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.

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 ...

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 ...

Now imagine an electron blown up to the size of the earth. Our experiment would have been able to see a layer 10,000 times thinner than a human hair, moved from the southern to the northern ...

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 ...

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, ...
