Indirect searches can be used to test dark matter models against expectedsignals in various channels, in particular antiprotons. With antiproton dataavailable soon at higher and higher energies, it is important to test the darkmatter hypothesis against alternative astrophysical sources, e.g. secondariesaccelerated in supernova remnants. We investigate the two signals fromdifferent dark models and different supernova remnant parameters, as forecastedfor the AMS-02, and show that they present a significant degeneracy.

Can AMS-02 discriminate the origin of an anti-proton signal?
