| Regge trajectories are plotted from the most recent data to show that linearity is not a necessary feature of the trajectories. Samples of Regge trajectories are calculated from the Maung-Kahana-Norbury bound state equation using the Nystrom-plus-correction method. The QCD string based Lund model is used to calculate the invariant cross sections of pions in the soft pT region. Invariant Hadron production cross sections in the hard pT region are calculated from the Feynman-Field perturbative QCD model. Theory and experimental data are parameterized so that the invariant production cross sections are usable to the NASA transport code. |
