“…The anisotropy of dark matter-induced nuclear recoils partially arises from the motion of the Earth through galactic dark matter halo, but can also arise from intrinsic anisotropies in the dark matter halo [3]. Therefore, measuring the direction of the nuclear recoils is not only a powerful handle to discriminate signal from background but also provides a whole class of new measurements of the dark matter's velocity distribution in the solar neighborhood [4][5][6][7][8][9].…”

Abstract:We discuss the relevance of directional detection experiments in the postdiscovery era and propose a method to extract the local dark matter phase space distribution from directional data. The first feature of this method is a parameterization of the dark matter distribution function in terms of integrals of motion, which can be analytically extended to infer properties of the global distribution if certain equilibrium conditions hold. The second feature of our method is a decomposition of the distribution function in moments of a model independent basis, with minimal reliance on the ansatz for its functional form. We illustrate our method using the Via Lactea II N-body simulation as well as an analytical model for the dark matter halo. We conclude that O(1000) events are necessary to measure deviations from the Standard Halo Model and constrain or measure the presence of anisotropies.

We study the amplitude for the spin-dependent WIMP scattering off nuclei by including the leading long-range two-body currents in the most important isovector contribution. We show that such effects are essentially independent of the target nucleus and, as a result, they can be treated as a mere renormalization of the effective nucleon cross section or, equivalently, of the corresponding effective coupling with values around 25%.
