The statistical hadronization model ThermalFist was applied to numerous hadron yields measured in p+p collisions at √ s = 8.8, 12.3, and 17.3 GeV, including recently published yields of ϕ and K 0 S -mesons, measured by the NA61/SHINE Collaboration. We consistently used the energydependent widths of Breit-Wigner mass distributions of hadronic resonances. The canonical treatment of particles with open strangeness combined with the grand canonical approach for non-strange particles gave a moderately reasonable agreement with the measured yields, quantified by χ 2 /NDF ≈ 2-7, only when the volume of strange particles was allowed to vary freely. This volume is found to be greater than the one for non-strange matter for all the studied energies. The predicted yields of some of not yet measured particles are provided.

“…K 0 S decays into neutral or charged pions contributing to the e ± cross sections. The NA61/SHINE experiment recently measured the production cross section of K 0 S from p + p collisions at s = 17.3 GeV [16]. With a similar strategy as for π + , at first we fix the p T and x F dependence of the cross section through a fit to the data of NA61/SHINE at s = 17.3 GeV, while the s behaviour is obtained by a second fit to the multiplicities at different s. For the K 0 L meson, the lack of experimental data does not allow to determine an independent model of the production cross section.…”

The cosmic-ray fluxes of electrons and positrons (e^{±}e±) are measured with high precision by the space-borne particle spectrometer AMS-02. To infer a precise interpretation of the production processes for e^{±}e± in our Galaxy, it is necessary to have an accurate description of the secondary component, produced by the interaction of cosmic-ray proton and helium with the interstellar medium atoms. We determine new analytical functions of the Lorentz invariant cross section for the production of e^±e± by fitting data from collider experiments. The total differential cross section d\sigma/dT_{e^±}(p+p→ e^±+X)dσ/dTe±(p+p→e±+X) is predicted with an uncertainty of about 5-7% in the energies relevant for AMS-02 positron flux. For further information about this work refer to [Phys. Rev. D 105, 123021 (2022)].

The cosmic-ray fluxes of electrons and positrons (e ± ) are measured with high precision by the space-borne particle spectrometer AMS-02. To infer a precise interpretation of the production processes for e ± in our Galaxy, it is necessary to have an accurate description of the secondary component, produced by the interaction of cosmic-ray proton and helium with the interstellar medium atoms. We determine new analytical functions of the Lorentz invariant cross section for the production of π ± and K ± by fitting data from collider experiments. We also evaluate the invariant cross sections for several other channels, involving for example hyperon decays, contributing at the few % level on the total cross section. For all these particles, the relevant 2 and 3 body decay channels are implemented, with the polarized µ ± decay computed with next-to-leading order corrections. The cross section for scattering of nuclei heavier than protons is modeled by fitting data on p + C collisions. The total differential cross section dσ/dT e ± (p + p → e ± + X) is predicted from 10 MeV up to 10 TeV of e ± energy with an uncertainty of about 5-7% in the energies relevant for AMS-02 positron flux, thus dramatically reducing the precision of the theoretical model with respect to the state of the art. Finally, we provide a prediction for the secondary Galactic e ± source spectrum with an uncertainty of the same level. As a service for the scientific community, we provide numerical tables and a script to calculate energy-differential cross sections.
