Azimuthal Correlations as a Test for Centrality in Heavy Ion Collisions
Nuclear Physics A
Azimuthal correlations of particles emitted in collisions between 197Au target nuclei and projectiles 36Ar (at and 129Xe (at have been measured with the MSU Miniball, a 4π phoswich array with a low detection threshold. Various impact parameter filters, based on the charge-particle multiplicity, transverse energy and midrapidity charge are tested by their ability to suppress collective motion as measured by the azimuthal correlations. The usefulness of a directivity cut in selecting central collisions for these systems is evaluated.
