Halo independent determination of the Dark Matter mass — •Yannick Müller and Thomas Schwetz — Institut für Kernphysik, Karlsruher Institut für Technologie (KIT)

A method for the determination of the mass of dark matter particles independent of any astrophysical parameters is presented. Hypothetical positive signals from two independent direct detection experiments are compared using distribution-free test statistics which neither require distribution fitting, nor data binning. Limitations in case of finite energy resolution as well as additional background sources are discussed. The method can also be generalized to analyze specific models such as the exchange of a light mediator particle.
