Introduction
This is a study motivated by a theory of dark matter, first suggested by Nima Arkani-Hamed in this arXiv paper. He and Neal Weiner made a study of how it could be seen in the LHC and wrote this paper.
We are currently working on the extension to this theory, suggested by Itay Yavin and others, which can be found here. This paper describes in detail the phenomenology of the resulting models.
The papers aim to explain the recent slew of surprising high-energy astrophysics observations made by the ATIC and PAMELA experiments, as well as the DAMA experiment.
