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

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

The results consistently yield the mass of an electron as approximately 9.1 x 10^-31 kg, regardless of variations in voltage and magnetic field strength. Additionally, ...

For context, that’s less than one-millionth the mass of an electron, which clocks in at a comparatively gargantuan 511,000 eV. So, yeah—neutrinos are ridiculously lightweight.

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.

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, ...

The KATRIN experiment began operations in 2019. It seeks to constrain the neutrino’s mass by looking at the energy spectrum of electrons and electron antineutrinos emitted by decaying tritium, a ...

The new LHCb measurement is based on a sample of 174,000 Z bosons decaying into pairs of muons, heavier relatives of the electron. The measurement resulted in a mass of 91,184.2 million ...
