Abstract

Standard descriptions of the Milky Way dark matter halo and the WIMP-nucleus scattering may be oversimplified. As a result, direct detection experiments like DEAP-3600 can miss important features in case of a future signal. Therefore, it is important to have detailed analysis of the diverse dark matter interactions, in addition to the standard spin-independent and -dependent couplings. In this study we made use of a Non-Relativistic Effective Field Theory which is a suitable framework for such purpose since it considers a palette of dark matternucleon interactions expressed in terms of effective operators. This research also examined how current DEAP-3600 limits are modified due to the presence of substructures in the solar neighborhood; such stellar debris have recently been observed by astronomical surveys like the Gaia satellite and they were assumed with some fraction of dark matter. The most important aspect our study reveals is that both particle physics and astrophysics uncertainties need to be treated together since non-linear effects manifest in exclusion curves.
