When Tritium decays into helium-3, it turns one neutron into a proton and one electron is released into an antineutrino (it has the same mass as a neutrino, but with the opposite spin).

An electron’s mass is about 511,000 electron volts.) In addition to a neutrino mass ceiling, there’s also a floor, based on laboratory particle physics experiments.

A final, key reason why the neutrino mass matters: It may help us understand the very question of what mass is. This thing we call mass seems to emerge when a particle — say, an electron — interacts ...

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

The neutrino’s mass limits the maximum energy the electron can have. Using measurements of a whopping 36 million electrons, the researchers looked for that subtle effect of the antineutrino’s ...

The KATRIN collaboration improved on its previous result by a factor of two. According to the experiment, the effective electron neutrino mass cannot be more than 0.45 electron volts, which is ...

Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN's Large Hadron Collider, using the FASER detector.

By measuring the energy of the electron, scientists can figure out how much energy the neutrino took away. This helps them estimate the neutrino’s mass. The trick is, this has to be done with ...

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.
