  "abstract": "Secondary astrophysical production of $e^+$ and $\\bar{p}$ cosmic rays is considered. Inclusive $\\pi$, $K$, and $\\bar{p}$ production cross sections in $pp$ collisions at large $\\sqrt{s}$ are parametrised using recent experimental data at LHC energies. The astrophysical production rate ratio $Q_{e^+}/Q_{\\bar{p}}$ is calculated for an input cosmic ray proton flux consistent with local measurements. At $10<E<100$$\\sim$GeV the cosmic ray flux ratio $J_{e^+}/J_{\\bar{p}}$ measured by AMS02 falls below the production rate ratio by about 50\\%, while at high energy $E>100$$\\sim$GeV the measured flux ratio coincides with the production rate ratio of the secondary source.",
