|The AMS-02 experiment has ushered cosmic-ray physics into precision era. Using the USINE code and an improved methodology, we extract the cosmic-ray transport parameters from the B/C data. We then derive a robust range of predictions for the secondary antiprotons flux, accounting for several sources of uncertainties and their correlations. Combined with a correlation matrix of systematic errors for the antiprotons data, we show that the latter are consistent with a secondary origin. We present key elements relevant to dark matter search in this channel, notably by pointing out the inherent difficulties in achieving predictions at the percent-level precision.
