Abstract

In this talk we will present some of the recent results from the experiments E863 and EMU12 using the BNL AGS Au-beam at 11.6 A GeV/c and the CERN SPS Pb-beam at 158 A GeV, respectively. Aspects on the particle production and on the target break-up will be discussed. The results are compared with model expectations. The lead data is here shown for the first time.

Abstract

Charged particle pseudorapidity density distributions in Au induced reactions in nuclear emulsion at 10.7 A GeV have been measured. In peripheral events the shower particle distribution exhibits a two peak structure while in central collisions it has a Gaussian shape. The spectator protons appear in the second peak in the pseudorapidity spectra and exhibits a broader momentum distribution than expected from Fermi motion. The produced particle yield in central collisions is not substantially different from phenomenological descriptions based on data from O and S induced reactions.

Abstract

Angular distributions of projectile-associated He fragments from Au induced reactions in nuclear emulsions at 10.7 A GeV have been measured with a precision of ±0.1 mrad. Two emission components are indubitably appearing, one representing fragmentation of a fermionic system while the other one exhibits large transverse momentum transfer. Possible explanations for the latter component are discussed.

Abstract

The recent status of the EMU01 experiment where nuclear emulsions are used as both target/detector material for horizontally exposed stacks and as detector for vertically exposed chamber plates is discussed. An investigation of the behaviour in the number of produced particles per participating nucleon reveal weak nonlinear effects for the most central collisions. Intermittency index can be obtained from the density distributions for S+Au and S+Ag interactions which corresponds to fractal dimensions somewhat smaller than unity.

Abstract

Using emulsion detectors a transverse-momentum analysis of projectile fragments has been performed in Au induced nuclear interactions at 11.6 A GeV/c. Evidence for collective flow of the projectile fragments has been obtained. Angular distributions of the principal vectors of projectile and target fragments have shown strong azimuthal correlation.
