| 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 $10100$$\sim$GeV the measured flux ratio coincides with the production rate ratio of the secondary source. |
