“…For SI form factors, it has been shown in Ref. [144] that the differences are ∼ 1 % for a light nucleus at 1 keV and ∼ 10 % for a heavy nucleus at 100 keV. The effect on the event rate is only minor for directional detection using CF 4 .…”

a b s t r a c tThe search for weakly-interacting massive particle (WIMP) dark matter is multi-pronged. Ultimately, the WIMP-dark-matter picture will only be confirmed if different classes of experiments see consistent signals and infer the same WIMP properties. In this work, we review the ideas, methods, and status of directdetection searches. We focus in particular on extracting WIMP physics (WIMP interactions and phasespace distribution) from direct-detection data in the early discovery days when multiple experiments see of order dozens to hundreds of events. To demonstrate the essential complementarity of different directdetection experiments in this context, we create mock data intended to represent the data from the nearfuture Generation 2 experiments. We consider both conventional supersymmetry-inspired benchmark points (with spin-independent and -dependent elastic cross sections just below current limits), as well as benchmark points for other classes of models (inelastic and effective-operator paradigms). We also investigate the effect on parameter estimation of loosening or dropping the assumptions about the local WIMP phase-space distribution. We arrive at two main conclusions. Firstly, teasing out WIMP physics with experiments depends critically on having a wide set of detector target materials, spanning a large range of target nuclear masses and spin-dependent sensitivity. It is also highly desirable to obtain data from low-threshold experiments. Secondly, a general reconstruction of the local WIMP velocity distribution, which will only be achieved if there are multiple experiments using different target materials, is critical to obtaining a robust and unbiased estimate of the WIMP mass.

“…The one-body structure factors F M AE and F Φ 00 AE were obtained using the full wave functions obtained in the nuclear shell-model calculations, while for F π only the diagonal contributions were considered, but taking into account the calculated shell-model occupancies. References [36,51] showed that the relevant coherent structure factors at low momentum transfer are not very sensitive to the nuclear structure details of the nuclei involved, suggesting that the associated uncertainties may be less relevant than the astrophysical ones [52].…”

Discriminating WIMP-nucleus response functions in present and future XENON-like direct detection experiments

The standard interpretation of direct-detection limits on dark matter involves particular assumptions of the underlying WIMP-nucleus interaction, such as, in the simplest case, the choice of a Helm form factor that phenomenologically describes an isoscalar spin-independent interaction. In general, the interaction of dark matter with the target nuclei may well proceed via different mechanisms, which would lead to a different shape of the corresponding nuclear structure factors as a function of the momentum transfer q. We study to what extent different WIMP-nucleus responses can be differentiated based on the q-dependence of their structure factors (or "form factors"). We assume an overall strength of the interaction consistent with present spin-independent limits and consider an exposure corresponding to XENON1T-like, XENONnT-like, and DARWIN-like direct detection experiments. We find that, as long as the interaction strength does not lie too much below current limits, the DARWIN settings allow a conclusive discrimination of many different response functions based on their q-dependence, with immediate consequences for elucidating the nature of dark matter.
