Connecting Direct Dark Matter Detection Experiments to Cosmologically
  Motivated Halo Models
  Several direct detection experiments, including recently CDMS-II, have
reported signals consistent with 5 to 10 GeV dark matter (DM) that appear to be
in tension with null results from XENON and LUX experiments; these indicate a
careful review of the theoretical basis, including the galactic DM velocity
distribution function (VDF). We establish a VDF parameter space from DM-only
cosmological simulations and illustrate that seemingly contradictory
experimental results can be made consistent within this parameter space. Future
experimental limits should be reported after they are marginalized over a range
of VDF parameters.
