Halo-Independent Analysis of Direct Dark Matter Detection Through
  Electron Scattering
  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. 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.
