The discovery that neutrinos have mass was groundbreaking. However, their absolute mass remains unknown. Neutrinoless double beta decay experiments aim to determine whether neutrinos are their own ...

AMHERST, Mass. – Physicists Andrea Pocar and Krishna Kumar of the University of Massachusetts Amherst, part of an international research team, recently reported results of an experiment conducted at ...

The Standard Model of Particle Physics is scientists' best understanding of the forces that describe how subatomic particles interact. The Standard Model encompasses four forces: the strong nuclear ...

Raymond Davis Jr. is dwarfed by the giant tank used by the Homestake detector in South Dakota, which first detected solar ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

Humble neutrinos — electrically neutral particles that glide through the universe, unaffected by the forces of nature — have helped to shape the cosmos. They play a role in nuclear fusion, radioactive ...

To say that neutrinos aren’t the easiest particles to study would be a bit of an understatement. Outside of dark matter, there’s not much in particle physics that is as slippery as the elusive “ghost ...

Back when it was theorized, scientists weren’t sure they would ever detect the neutrino; now they’re searching for a version of the particle that could be even more elusive. In Germany in 1930, a ...
