    "abstract": "We investigate the production of pions in heavy-ion collisions in the energy\nrange of $1$ - $2$ GeV/A. The dynamics of the nucleus-nucleus collisions is\ndescribed by a set of coupled transport equations of the\nBoltzmann-Uehling-Uhlenbeck type for baryons and mesons. Besides the $N(938)$\nand the $\\Delta(1232)$ we also take into account nucleon resonances up to\nmasses of $1.9 GeV/c^2$ as well as $\\pi$-, $\\eta$- and $\\rho$-mesons. We study\nin detail the influence of the higher baryonic resonances and the\n$2\\pi$-production channels ($NN\\to NN \\pi\\pi$) on the pion spectra in\ncomparison to $\\pi^-$ data from $Ar + KCl$ collisions at $1.8$ GeV/A and\n$\\pi^0$-data for $Au+Au$ at 1.0 GeV/A. We, furthermore, present a detailed\ncomparison of differential pion angular distributions with the BEVALAC data for\nAr + KCl at 1.8 GeV/A. The general agreement obtained indicates that the\noverall reactions dynamics is well described by our novel transport approach.",
