The Migdal effect has been used along with nuclear direct detection experiments to constrain dark matter models in the sub-GeV region. By utilizing the Migdal effect with data from the XENON1T and DarkSide-50 experiments, we constrained the dipolar interactions of dark matter with visible matter. We find that the Migdal limit sets the strongest constraints on dark matter at the Sub-GeV scale. The complementarity of the Migdal effect with dark matter-electron scattering processes is observed.

摘要

The Migdal effect has been used along with nuclear direct detection experiments to constrain dark matter models in the sub-GeV region. By utilizing the Migdal effect with data from the XENON1T and DarkSide-50 experiments, we constrained the dipolar interactions of dark matter with visible matter. We find that the Migdal limit sets the strongest constraints on dark matter at the Sub-GeV scale. The complementarity of the Migdal effect with dark matter-electron scattering processes is observed.
