Description

One of the simplest particle physics realizations of self-interacting dark matter is a WIMP interacting with a MeV-scale scalar mediator. While this scenario is already largely excluded for dark matter masses above ~5 GeV by null searches from various direct detection experiments, future low-threshold detectors such as CRESST and CDMS could be sensitive to so far unexplored regions of the parameter space in which the WIMP has a mass of only a few GeV. In this talk I will demonstrate that by combining spectral information from several targets, these future experiments could be able to simultaneously reconstruct both the dark matter and mediator mass, and thereby offer the exciting possibility to probe astrophysical properties of dark matter using direct detection searches.
