Displaying results of direct detection dark matter experiments free of astrophysical uncertainties — •Ludwig Rauch and Collaboration XENON — Max Planck Institut für Kernphysik, Heidelberg

A number of experiments try to measure WIMP interactions by using different detector technologies and target elements. Hence, energy thresholds and sensitivities to light or heavy WIMP masses differ. However, due to large systematic uncertainties in the parameters defining the dark matter halo, a comparison of detectors is demanding. By mapping experimental results from the traditional cross section vs. dark matter mass parameter-space into a dark matter halo independent phase space, direct comparisons between experiments can be made. This is possible due to the monotonicity of the velocity integral which enables to combine all astrophysical assumptions into one parameter common to all experiments. In this talk the motivation as well as the mapping method will be explained based on the XENON100 data.
