Event Details & Abstract: 

An intriguing theoretical possibility is that dark matter is a neutral composite bound state of electroweak-charged constituents. I will discuss some general features of composite dark matter, and then present a specific model, "stealth dark matter", in which direct detection is mediated by Higgs boson exchange and by the dimension-7 electromagnetic polarizability of the dark matter candidate. Lattice calculations in SU(4) gauge theory, used to determine important matrix elements for this model, will also be presented.
