Dark matter substructures affect dark matter-electron scattering in xenon-based direct detection experiments

Understand

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.
