An elongation versus departure from axial symmetry (triaxiality) plot showing distinctive differences in the shapes of the parent (germanium-76, “rigid”) and daughter (selenium-76, “soft”) nuclei for ...

Double beta decay research represents a pivotal field at the intersection of nuclear physics and particle physics, probing the fundamental nature of neutrinos and their role in the matter–antimatter ...

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 ...

Japan’s Super-Kamiokande detector, a massive underground neutrino observatory, has completed its most sensitive search yet ...

Double beta decay experiments, solar-neutrino projects, detectors to observe accelerator-produced neutrinos at great distances, experiments to detect the dark matter that holds together our own galaxy ...

Off the southern coast of Lake Baikal in Siberia, an underwater telescope has been installed to detect neutrinos. For years physicists debated whether the neutrino had mass or was massless like the ...

Halloween horror movies often feature ghosts slipping through walls unnoticed by those in the dwellings they haunt. At the Department of Energy’s Pacific Northwest National Laboratory, scientists seek ...

Sheltered underneath nearly a mile of rock in Abruzzo, Italy, scientists are hard at work unraveling the secrets of the universe's smallest bits of matter. When a radioactive process called beta decay ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

The problem remains that majorons, like all hypothetical dark matter particles, have never been detected and experiments keep putting finer and finer limits on their potential existence. I'm almost ...

The neutrino is now central to elementary particle physics, astrophysics, and cosmology. Neutrinos play a key role in theories that unify the elementary particles and forces. They yield clues about ...
