Large-scale nuclear structure calculations for spin-dependent WIMP
  scattering with chiral effective field theory currents
  We perform state-of-the-art large-scale shell-model calculations of the
structure factors for elastic spin-dependent WIMP scattering off 129,131Xe,
127I, 73Ge, 19F, 23Na, 27Al, and 29Si. This comprehensive survey covers the
non-zero-spin nuclei relevant to direct dark matter detection. We include a
pedagogical presentation of the formalism necessary to describe elastic and
inelastic WIMP-nucleus scattering. The valence spaces and nuclear interactions
employed have been previously used in nuclear structure calculations for these
mass regions and yield a good spectroscopic description of these isotopes. We
use spin-dependent WIMP-nucleus currents based on chiral effective field theory
(EFT) at the one-body level and including the leading long-range two-body
currents due to pion exchange, which are predicted in chiral EFT. Results for
all structure factors are provided with theoretical error bands due to the
nuclear uncertainties of WIMP currents in nuclei.
