Cross Sections for Antiprotons in Hydrogen, Beryllium, Carbon, and Lead

Antiproton Flux, Antiproton-to-Proton Flux Ratio, and Properties of Elementary Particle Fluxes in Primary Cosmic Rays Measured with the Alpha Magnetic Spectrometer on the International Space Station

“…The systematic error from the cross section uncertainties is estimated by varying thep and p interaction cross sections in the Monte Carlo simulation within the accuracy of the cross section measurements [32,33]. The corresponding systematic error onÃp is found to be 4% at 1 GV and ∼1% above 50 GV.…”

“…The systematic errors on the folded acceptancesÃp and A p originate from the uncertainties in the interaction cross sections for protons and antiprotons in the detector materials [32,33] and the uncertainties in the migration matrices Mp ij and M p ij . The systematic error from the cross section uncertainties is estimated by varying thep and p interaction cross sections in the Monte Carlo simulation within the accuracy of the cross section measurements [32,33].…”
