Dark Matter and the Effective Theory of Direct Detection

Friday November 17, 2017
3:30 pm


 Presenter:  Wick Haxton, UCB
 Series:  Physics and Astronomy Colloquium
 Abstract:  A great deal of effort is being expended to develop detectors capable of identifying heavy
dark matter particles through the nuclear recoils they induce when scattering in ordinary matter.
An interesting question is what can and cannot be learned about the underlying particle
physics of dark matter from such experiments. I describe an approach in which the tools
of effective theory are used to determine both nucleon-level and nuclear-level operators for
this process. The unusual kinematics -- energy transfers are minimal while momentum
transfers are large, on the scale of the inverse nuclear size -- makes the nuclear response
more interesting than one might naively assume.
