Jp. Schneider et al., PARAMETERIZATION OF SPECTRAL DISTRIBUTIONS FOR PION AND KAON PRODUCTION IN PROTON-PROTON COLLISIONS, The Astrophysical journal. Supplement series, 97(2), 1995, pp. 571-574
Accurate semi-empirical parameterizations of the energy-differential c
ross sections for charged pion and kaon production from proton-proton
collisions are presented at energies relevant to cosmic rays. The para
meterizations depend on the outgoing meson momentum and also the proto
n energy, and are able to be reduced to very simple analytical formula
s suitable for cosmic-ray transport.
