    "abstract": "The S-matrix approach is used to calculate charged as well as neutral pion\nproduction reactions from NN scattering, with the same set of underlying\nprocesses and interactions. The chiral perturbation theory piN scattering\namplitude is used. For the nucleon-nucleon distortions a newly developed\nrealistic potential within the Bonn family of potentials, valid well above the\npion production threshold, is considered. In the pi+ production case, the NN\npotential, the piN relative p-waves and the treatment of the exchanged pion\nenergy build up the observed cross-section strength.",
