“…In reference [2], the parameterizations of equations (1) - (3) were compared only to nine data points from Whitmore [3] at p lab = 12, 19 and 24 GeV. In the present work, they are compared to the Whitmore data at 69, 102, 205 and 303 GeV, as well as to some other low energy data [4][5][6][7], and the data point at p lab = 954 MeV corresponding to T lab = 400 MeV, of Abd El-Samad et al [8].…”

Total cross section parameterizations for neutral and charged pion production in nucleon-nuelcon collisions are compared to an extensive set of experimental data over the projectile momentum range from threshold to 300 GeV. Both proton-proton and proton-neutron reactions are considered. Good agreement between parameterizations and experiment is found, and therefore the parameterizations will be useful for applications, such as transport codes.PACS numbers: 13.75.CsMany astrophysical gamma rays and neutrinos result from the decay of pions produced in interstellar protonproton (pp) collisions [1]. Most of the muons that travel through the Earth's atmosphere and reach ground level are also the result of pion decay. In modeling astrophysical and cosmic ray sources, one requires an accurate knowledge of pion production cross sections from nucleon-nucleon collisions. Furthermore, because these cross sections are most often used as input to transport codes, it is very useful to have them in a simple, parameterized form, so that the transport codes can run efficiently. Such parameterizations are the subject of this Brief Report. Previous parameterizations have been developed [2] for total pion production cross sections in pp collisions. However, these results were compared to only nine experimental data points, and therefore one did not have much confidence in their validity. In the present work, these same parameterizations are compared to approximately thirty experimental data points. The good agreement obtained gives greater confidence in the use of these parameterizations.The total inclusive cross section for pion production in proton-proton collisions has been parameterized as [2] σ pp→π + X = 0.00717 + 0.0652 log T lab T lab + 0.162
