Supersplit supersymmetry

From Wikipedia, the free encyclopedia

Supersplit supersymmetry was conceived as an April Fool's day joke in 2005 by a group of some of the leading young theoretical high energy physicists. It was meant as a parody of split supersymmetry. In the model, the particles in split supersymmetry (beyond those of the Standard Model) are decoupled leaving no trace at low energies, therefore leaving just the Standard Model. It argued that the 30% accuracy of gauge coupling unification in the Standard Model is on par with the 1% accuracy in the MSSM or Split Supersymmetry. It also used the well-known possibility that a Peccei-Quinn axion could be the dark matter of the universe. As a serious scientific theory, it leads to no new predictions beyond the Standard Model and therefore is an unverifiable theory. As a social commentary, it demonstrates the uneasiness in the high energy physics community about the direction some model building is heading.

Curiosly, the original paper has been cited as a true model by few respectful theoretical physicists[1].
