Neutrinos and antineutrinos are elementary particles with small but unknown mass. High-precision atomic mass measurements at the Accelerator Laboratory of the University of Jyväskylä, Finland, have ...

Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process ...

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 ...

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 ...
