Composite models of self-interacting dark matter

Title: Composite models of self-interacting dark matter

Presenter: Jim Kline

Abstract: There are interesting hints that standard cold dark matter does not correctly predict the small scale structure of the universe, while dark matter with strong self-interactions may do so.  Models in which the dark matter is composite--dark analogs of atoms, mesons, nucleons, glueballs--can naturally have large self-interactions.  I will briefly review the experimental hints for dark matter self-interactions, and discuss implications of these models for direct detection, the CMB, nucleosynthesis, and the LHC.
