Description

Global analyses of different dark matter searches are necessary to determine the status of dark matter models. Highly accurate antiproton measurements from AMS-02 would add valuable information to such global analyses. I will present an analysis pipeline for fast and accurate antiproton likelihoods in global scans. The pipeline consists of a neural network emulator for antiproton flux simulations, and a likelihood calculator for accurate treatment of correlations and marginalization of propagation uncertainties. I will conclude with the status of scalar singlet dark matter, considering new direct detection and LHC likelihoods in addition to the antiproton likelihood.
