Abstract
The directed and elliptic flow of protons and negative pions in4.2A GeV c-1C + C collisions is studied using the Fourier analysis of azimuthaldistributions. It is found that the protons exhibit pronounced directedflow, while the flow of pions is either non-existent or too weak to bedetected experimentally. Also, it is found that in the entire rapidityinterval the elliptic flow is very small if not zero. These results areconfirmed by the quark-gluon-string model (QGSM)and the relativistic transport model (ART 1.0), except that these modelspredict a very weak antiflow of pions. The more detailed comparison withthe QGSM suggests that the decay of resonances and rescattering ofsecondaries dominantly determine the proton and negative pion flow atthis energy.
