gammaproton
Gammaproton is a hypothetical particle that has been proposed in some theoretical extensions of the Standard Model of particle physics. It is conceived as a particle that mediates a force between gamma rays and protons, or perhaps as a resonance state involving these particles. The concept of a gammaproton is not part of the established Standard Model, and there is no experimental evidence to support its existence.
The theoretical motivations for postulating such a particle often arise from attempts to explain phenomena that
Alternatively, the term might refer to a composite particle, a bound state of a gamma ray and
