Supersplit supersymmetry
Supersplit supersymmetry was conceived as an April Fool's Day joke in 2005 by a group of young theoretical high energy physicists. It was meant as a parody of split supersymmetry.
The model proposed particles which are decoupled, leaving no trace at low energies, therefore leaving just the Standard Model. The paper 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 is therefore unverifiable. As a social commentary, it demonstrates the uneasiness in the high energy physics community about the direction some model building is heading.
Despite the original intent as a ridiculous proposal, the original paper has been cited by few theoretical physicists.
Very recently, a paper by Giudice and Strumia has presented the same idea under the name 'high scale supersymmetry'.
