Can AMS-02 discriminate the origin of an anti-proton signal?
  Indirect searches can be used to test dark matter models against expected
signals in various channels, in particular antiprotons. With antiproton data
available soon at higher and higher energies, it is important to test the dark
matter hypothesis against alternative astrophysical sources, e.g. secondaries
accelerated in supernova remnants. We investigate the two signals from
different dark models and different supernova remnant parameters, as forecasted
for the AMS-02, and show that they present a significant degeneracy.
