Energy densities, target fragmentation and pion correlations in ultrarelativistic H. I. C., as predicted by SPACER
Abstract
SPACER, a spacetime version of FRITIOF is applied to the calculation of the flow velocity field, local rest densities and energy densities for the case of 14.5 AGeV Si^{28} + Au^{197} collisions as well as 200 AGeV O^{16}, S^{32} + Au^{197} collisions. At CERN energies, the model predicts a 2530% overall increase in local rest (energy) densities, when using S^{32} instead of the O^{16} projectile. SPACER suggests a strong spectator fragmentation. This effect is taken into account with the help of a simple analytic model, which implies an experimentally observed scaling in the angular distribution of target associated particles. SPACER predicts that the shape of the twopion correlation function C( Q_{I}) is exponential with chaocity parameter close to 1.
