fermionien

Fermionien is a term found in some theoretical discussions and in German-language sources to denote a class of fermionic particles. In this usage, Fermionien are particles with half-integer spin that obey Fermi-Dirac statistics and the Pauli exclusion principle, placing them in the same broad category as electrons, quarks, and neutrinos. The label is not part of the standard nomenclature in mainstream particle physics, where the conventional term fermions is typically used.

In speculative or extended-model contexts, Fermionien may be invoked to discuss new families of matter, hidden sectors, or exotic symmetry structures. They are treated as matter fields that transform under the gauge groups of a given theory in ways analogous to known fermions, but with model-dependent properties such as mass, charges, or coupling patterns. In science fiction, the term is sometimes employed to describe novel fermionic species or excitations to illustrate ideas about fundamental matter.

Real-world fermions, which include leptons and quarks, share the essential spin-statistics properties attributed to Fermionien in these discussions. The concept of Fermionien therefore serves as a general label to emphasize common fermionic behavior while allowing for theoretical diversity in how such particles might interact or fit into broader theories.

Current status: there is no experimental evidence for a distinct class formally called Fermionien. The term remains a niche or fictional label rather than a standard term in particle physics.
