Azimuthal Correlations of Transverse Energy for Pb on Pb at 158 GeV/Nucleon

Abstract

Azimuthal correlations have been studied in heavy ion reactions over a wide range of beam energies. At low incident energies up to 100 MeV/nucleon where collective effects like the directed sidewards flow are generally small, azimuthal correlations provide a useful tool to determine the reaction plane event by event [1]. In the energy regime of the BEVALAC (up to 1 GeV/nucleon for heavy ions) particular emission patterns, i.e. azimuthal correlations of nucleons and light nuclei with respect to the reaction plane, have been associated with the so called squeeze out [2] and sidesplash [3] effects. These effects are of particular interest because of their sensitivity to the equation of state at the high baryon density which is build up during the collision process [4]. Angular distributions similar to the squeeze out have been observed for pions at the SIS in Darmstadt [5, 6] as well as from the EOS — collaboration [7]. Recently also the sideward flow was measured for pions and kaons [7, 8]. However, the origin of the signal in the case of produced mesons is thought to be of a different nature than that for the nucleon flow [9, 10].
