This paper reports an investigation of the two-particle and three-particle short-range angular correlations among the target fragments produced in ²⁸Si-AgBr interactions at 14.5 AGeV. The experimental data have been compared with Monte Carlo simulated events to extract dynamical correlations. The data exhibit strong two-particle and three-particle correlations among the target fragments. The data further indicate the occurrence of the so-called side splash phenomena and disfavour the evaporation model.
