| description | The secondary astrophysical production of e+ and p¯ cosmic rays is considered. Inclusive π-, K-, and p¯-production cross sections in pp collisions at large s are parametrized using recent experimental data at LHC energies. The astrophysical production-rate ratio Qe+/Qp¯ is calculated for an input cosmic ray proton flux consistent with local measurements. At 10<E<100 GeV, the cosmic ray flux ratio Je+/Jp¯ measured by AMS02 falls below the production-rate ratio by about 50%, while at high energy E>100 GeV, the measured flux ratio coincides with the production-rate ratio of the secondary source. |

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.arXiv:1709.04953oai:cds.cern.ch:22881032017-09-14 |
