“…These simulation results demonstrate clearly that, even though the WIMP Galactic velocity distribution has been here most simply assumed as isotropic, the angular distribution of the 3-D velocity of WIMPs impinging on our detectors would already be more complicated than a highly concentrated WIMP wind 6 . Furthermore, ...…”

“…Direct Dark Matter (DM) detection experiments aiming to observe scattering signals of Weakly Interacting Massive Particles (WIMPs) off target nuclei by measuring recoil energies deposited in an underground detector would still be the most reliable experimental strategy for identifying Galactic DM particles and determining their properties [1,2,3,4,5,6]. For either providing exclusion limits with null results or reconstructing WIMP properties with positive scattering events, an estimate of the total or the differential event rate for elastic WIMP-nucleus scattering is essential and crucial [1,3,4,6].…”

No room to hide: implications of cosmic-ray upscattering for GeV-scale dark matter

The irreducible upscattering of cold dark matter by cosmic rays opens up the intriguing possibility of detecting even light dark matter in conventional direct detection experiments or underground neutrino detectors. The mechanism also significantly enhances sensitivity to models with very large nuclear scattering rates, where the atmosphere and rock overburden efficiently stop standard non-relativistic dark matter particles before they could reach the detector. In this article, we demonstrate that cosmic-ray upscattering essentially closes the window for strongly interacting dark matter in the (sub-)GeV mass range. Arriving at this conclusion crucially requires a detailed treatment of both nuclear form factors and inelastic dark matter-nucleus scattering, as well as including the full momentum-transfer dependence of scattering amplitudes. We illustrate the latter point by considering three generic situations where such a momentum-dependence is particularly relevant, namely for interactions dominated by the exchange of light vector or scalar mediators, respectively, and for dark matter particles of finite size. As a final concrete example, we apply our analysis to a putative hexaquark state, which has been suggested as a viable baryonic dark matter candidate. Once again, we find that the updated constraints derived in this work close a significant part of otherwise unconstrained parameter space.

Recent sky surveys have discovered a large number of stellar substructures. It is highly likely that there are dark matter (DM) counterparts to these stellar substructures. We examine the implications of DM substructures for electron recoil (ER) direct detection (DD) rates in dual phase xenon experiments. We have utilized the results of the LAMOST survey and considered a few benchmark substructures in our analysis. Assuming that these substructures constitute 10% of the local DM density, we study the discovery limits of DM-electron scattering cross sections considering one kg-year exposure and 1, 2, and 3 electron thresholds. With this exposure and threshold, it is possible to observe the effect of the considered DM substructure for the currently allowed parameter space. We also explore the sensitivity of these experiments in resolving the DM substructure fraction. For all the considered cases, we observe that DM having mass $$ \mathcal{O}(10) $$ O 10 MeV has a better prospect in resolving substructure fraction as compared to $$ \mathcal{O}(100) $$ O 100 MeV scale DM. We also find that within the currently allowed DM-electron scattering cross-section; these experiments can resolve the substructure fraction (provided it has a non-negligible contribution to the local DM density) with good accuracy for $$ \mathcal{O}(10) $$ O 10 MeV DM mass with one electron threshold.
