In this talk, we discuss the physics modeling of antiproton spectra arising from dark matter (DM) annihilation or decay in a model-independent manner. The modeling of antiproton spectra contains some intrinsic uncertainties related to QCD parton showers and hadronisation of baryons. We briefly assess the sources of these uncertainties and their impact on antiproton energy spectra for a few selected DM scenarios. The results are provided in tabulated form for future analyses.

Abbreviated titleCompTools 2021
OtherThis workshop aims to review the state-of-the-art tools for high energy physics and cosmology.
The workshop consists of short sessions over 5 days together with software demo and several discussion sessions.

The following themes will be covered at the workshop:

Higgs and Collider physics
Dark matter
Flavour physics and precision tests
General tools (Fitting tools, recast tools, spectrum generators, etc...)

The program will consist of both invited talks and contributed talks and tutorials.
