Effective theory and the nuclear physics of dark matter detection

It is known that the majority (about 80%) of the matter in the universe is not visible, but rather a hypothetical "Dark Matter". The existence of Dark Matter has been postulated to explain the discrepancies between the estimated mass of visible matters in the galaxies, and their gravitational effects. Although it has been postulated for over 70 years, and has been commonly accepted by most scientists, the essence of the Dark Matter has not yet been understood. In particular, we still do not know what constitutes the Dark Matter. Direct detection of the Dark Matter is therefore one of the most important issues in physics.

Direct Dark Matter

Abstract Sub-GeV mass dark matter particles whose collisions with nuclei would not deposit sufficient energy to be detected, could instead be revealed through their interaction with electrons. Analyses of data from direct detection experiments usually require assuming a local dark matter halo velocity distribution. In the halo-independent analysis method, properties of this distribution are instead inferred from direct dark matter detection data, which allows then to compare different data without making any assumption on the uncertain local dark halo characteristics. This method has so far been developed for and applied to dark matter scattering off nuclei. Here we demonstrate how this analysis can be applied to scattering off electrons.
