The possibility of a hidden sector of particle physics that lies beyond the energy range of the Standard Model has been recently advocated by many authors. A bizarre implication of this conjecture is the emergence of a continuous spectrum of massless fields with non-integral scaling dimensions called "un-particles". The purpose of this Letter is to show that the idea of "un-particles" was considered in at least two previous independent publications, prior to its first claimed disclosure.

The Standard Model (SM) is a highly successful theoretical framework that describes the relationships among all known elementary particles and the attributes ...
