Flow due to nonlocal correlations in heavy-ion reactions — •K. Morawetz — Institute of Physics, Chemnitz University of Technology, 09107 Chemnitz, Germany — Max-Planck-Institute for the Physics of Complex Systems, Nöthnitzer Str. 38, 01187 Dresden, Germany

The flow parameters like squeezing and flow angle are systematically calculated for ALADIN-INDRA data on Au+Au. The nonlocal extension of BUU [1,2] is compared with standard simulations. A visible effect of nonlocal correlations is seen and it is found a better agreement with the data. This underlines the improvement by nonlocal extensions as found earlier when comparing with data of charge density distribution [3] or particle spectra [4].
