Description
Despite decades of global effort, DM particles have so far evaded all attempts of direct detection. This may suggest that DM particles are too light to be detected with current experiments. The experimental sensitivity towards low dark matter mass can be improved by electronic excitation induced by nuclear recoil, a process known as the Migdal effect. We are developing a general formalism to describe DM-nucleon inelastic scattering processes such as the Migdal effect. Building on the earlier work, we focus on the directional dependence due to the crystal structure of the target material, and the resulting diurnal modulation of the signal.
