Neutroneids
Neutroneids are a hypothetical class of subatomic particles that are thought to interact primarily through the strong nuclear force. They are predicted by some theoretical extensions of the Standard Model of particle physics, but have not yet been experimentally observed. The concept of neutroneids arises in theories that attempt to unify gravity with other fundamental forces or to explain phenomena like dark matter. Their properties, such as mass and charge, are not definitively known and depend on the specific theoretical framework in which they are proposed. If they exist, neutroneids would be distinct from known particles like neutrons, which are baryons composed of quarks. The search for neutroneids is an active area of theoretical research, and future experiments might provide clues about their potential existence.
