Neutrinos are elementary particles that are predicted to be massless by the standard model of particle physics, yet their ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether ...

Bind an electron to a reference ion—the team used the “hydrogen-like” carbon nucleus, stripped down to a single electron. The nucleus of that ion has a known, precise mass.

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

Using a novel technique, scientists have greatly improved the precision with which they can measure the mass of an electron, a new study reports.

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.

The KATRIN experiment in Germany nearly halved the maximum possible mass for neutrinos, setting it at 0.45 electron volts.

It seeks to constrain the neutrino’s mass by looking at the energy spectrum of electrons and electron antineutrinos emitted by decaying tritium, a radioactive isotope of hydrogen.

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

The mass of an electron is very small compared to a proton or a neutron. 1 840 electrons have the same mass as 1 proton or neutron. Since the nucleus only contains protons and neutrons, most of ...
