Description

In this talk, I discuss the progress on the particle physics modeling of anti-proton spectra from dark matter indirect detection searches and the QCD uncertainties on these predictions. First, I discuss the challenges in the measurements of baryon differential yields at LEP and the way we used to deal with these. Then, we discuss the up-to date fits of the fragmentation function including baryon component and the resulting QCD uncertainties. The results of this study will be published on Zenodo and GitHub.
