Enpartikel
Enpartikel is a hypothetical elementary particle that has been proposed in some theoretical extensions of the Standard Model of particle physics. It is often associated with theories attempting to unify fundamental forces or explain phenomena not accounted for by the Standard Model, such as dark matter. The term "enpartikel" itself is not a widely recognized or standardized term in mainstream physics literature. It may refer to a specific concept within a particular theoretical framework or could be a neologism.
The properties of an enpartikel would depend entirely on the specific theoretical model in which it is
Because it is a hypothetical construct, there is no experimental evidence for the existence of an enpartikel.
