Does the proton decay? While this was a famous prediction of Grand Unified Theories (GUTS) developed in the 1970s and 1980s, experimentalists have ruled it out—or rather, put lower limits on its mean ...

All the matter we know of in our Universe is made of both fundamental and composite particles. However, only a few of the fundamental particles are observed to be stable and not to decay into other ...

The observation of a resonance in the boron-11 nucleus suggests that the proton emission from beryllium-11 is a two-step process rather than a dark matter decay channel. The discovery of an exotic ...

Two independent teams of nuclear physicists have found evidence for a new form of radioactivity involving the simultaneous emission of two protons. Researchers at the GANIL laboratory in France and ...

According to the Standard Model, protons are inherently stable and will not decay into other particles. Other theories, however, contend that they do. If true, that means that in the astronomically ...

AT SOME point in our lives, most of us learn that atoms are comprised of three types of particle: neutrons, protons and electrons. Each has distinct properties. The electron and proton have opposite ...

The decay of proton-rich nuclei by the emission of a single proton has been known about for some time, and is well understood. The latest observation of two-proton emission, however, will provoke some ...

A few days ago I wrote about how different measurements of the Hubble parameter gave results that didn't quite agree. It's not the only example of such an experimental disagreement. In fact, one of ...

Researchers have observed a rare nuclear decay. Namely, the team measured low-kinetic-energy protons emitted after the beta decay of a neutron-rich nucleus beryllium-11. Researchers from the National ...
