Fermid

Fermid is a theoretical particle that has been proposed in some extensions of the Standard Model of particle physics. It is often discussed in the context of supersymmetry, a theory that postulates a symmetry between fermions and bosons. In such theories, every known fundamental particle is predicted to have a superpartner with a different spin. The fermid is a hypothetical superpartner of a fermion, meaning it would be a boson. Conversely, a fermion is the superpartner of a boson. The term "fermion" itself is a portmanteau of "fermion" and "boson".

The properties of fermids, such as their mass and interactions, depend on the specific supersymmetric model being considered. Currently, there is no experimental evidence for the existence of fermids. Searches for supersymmetric particles are ongoing at particle accelerators like the Large Hadron Collider, but no definitive signals have been observed to date. If fermids were discovered, it would provide strong support for supersymmetry and could help solve some of the outstanding mysteries in particle physics, such as the nature of dark matter. The study of fermids remains an active area of theoretical and experimental research.
