Connecting Direct Dark Matter Detection Experiments to Cosmologically Motivated Halo Models    [PDF]

Several direct detection experiments, including very recently CDMS-II, have reported signals consistent with 5 to 10 GeV dark matter that appear to be in tension with null results from XENON experiments. We establish the cosmologically motivated parameter space for the Galactic dark matter velocity distribution function (VDF) and illustrate that seemingly contradictory experimental results with the standard analysis can be made consistent with each other within this VDF parameter space. Future experimental limits should be reported for a range of well-motivated VDFs.
