Connecting direct dark matter detection experiments to cosmologically motivated halo models
Physical Review D, 2014•APS
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 …

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.
