Indirect Detection of Self-Interacting Asymmetric Dark Matter
  Self-interacting dark matter resolves the issue of cuspy profiles that appear
in non-interacting cold dark matter simluations; it may additionally resolve
the so-called "too big to fail" problem in structure formation. Asymmetric dark
matter provides a natural explanation of the comparable densities of baryonic
matter and dark matter. In this paper, we discuss unique indirect detection
signals produced by a minimal model of self-interacting asymmetric scalar dark
matter. Through the formation of dark matter bound states, a dark force
mediator particle may be emitted; the decay of this particle may produce an
observable signal. We estimate the produced signal and explicitly demonstrate
parameters for which the signal exceeds current observations.
