An international collaboration including scientists at the Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL) solved a 50-year-old puzzle that explains why beta decays of atomic ...

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 ...

How long did it take our Sun to form in its stellar nursery? Scientists are now closer to an answer. They succeeded in the measurement of the bound-state beta decay of fully-ionized thallium ions at ...

The observation of neutrinoless double beta decay would suggest that, by itself, the Standard Model Higgs cannot give mass to neutrinos. Last year, physicists discovered the long-sought Higgs boson, ...

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 ...

Neutrino-free process: observing neutrinoless double beta decay could shed light on important mysteries of particle physics. A new technique to enable the detection of a hypothetical process called ...

For the best part of 30 years, physicists have been looking for a very rare nuclear process known as neutrinoless double beta decay. With discovery still elusive, an international team of researchers ...

For the first time, scientists observe a new and rare decay mode where oxygen-13 breaks into three helium nuclei and a proton following beta decay. Scientists have previously observed interesting ...

Deep under a mountain in Italy, researchers continue to push the boundaries of science with an experiment that could rewrite the Standard Model of Particle Physics. Standard “double beta decay” is ...
