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 ...

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 ...

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 ...

The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons.

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic ...

Nuclear physicist Evangeline Downie hadn’t planned to study one of the thorniest puzzles of the proton. But when opportunity knocked, Downie couldn’t say no. “It’s the proton,” she exclaims. The ...
