| Abstract: | I discuss the impact of QCD uncertainties from parton-shower modeling and fragmentation functions on the dark-matter interpretations of various excesses reported on by AMS-02 and Fermi-LAT. After discussing the physics modeling for the spectra, I discuss a conservative estimate of these uncertainties using a set of variations around the optimal best-fit points. It is found that these uncertainties can alter the best-fit of the mass by about 7-60 GeV depending on the nominal value of the dark matter mass and the thermally-averaged cross section by about 7-10% depending on the annihilation channel. The tables along with code snippets can be found on Github (https://github.com/ajueid/qcd-dm.github.io). |
