    "abstract": "Triple differential cross sections of pions in heavy ion collisions at 1\nGeV/nucl. are studied with the IQMD model. After discussing general properties\nof $\\Delta$ resonance and pion production we focus on azimuthal correlations:\nAt projectile- and target-rapidities we observe an anticorrelation in the\nin-plane transverse momentum between pions and protons. At c.m.-rapidity,\nhowever, we find that high $p_t$ pions are being preferentially emitted\nperpendicular to the event-plane. We investigate the causes of those\ncorrelations and their sensitivity on the density and momentum dependence of\nthe real and imaginary part of the nucleon and pion optical potential.",
