Dark Matter Direct Detection Dark Matter: Direct Detection


Felix Kahlhoefer (University of Oxford)


Uncertainty in the local dark matter velocity distribution is a key difficulty in the analysis of data from direct detection experiments. In my talk, I will propose a completely new approach for dealing with this uncertainty, which does not involve any assumptions about the structure of the dark matter halo. Given a dark matter model, this approach yields the velocity distribution which best describes a set of direct detection data as a finite sum of streams with optimized speeds and densities. The method is conceptually simple and numerically very efficient. As a possible application I will discuss how to use the method to determining the ratio of proton to neutron couplings of dark matter from a hypothetical set of future data.
