Neutrinos and antineutrinos are elementary particles with small but unknown mass. High-precision atomic mass measurements have revealed that beta decay of the silver-110 isomer has a strong potential ...

Add Yahoo as a preferred source to see more of our stories on Google. A tank of the purest water, buried under kilometers of rock in Ontario, Canada, flashed as a barely detectable particle slammed ...

Scientists in Finland have found a rare type of nuclear decay that could help answer one of physics’ biggest open questions: the mass of the electron‑antineutrino. Neutrinos are tiny, almost massless ...

Neutrino mass measurements remain one of the most challenging endeavours in contemporary physics. Direct measurement techniques, particularly those probing the endpoint of the tritium β-decay spectrum ...
