Some recent results in Au+Au collisions at AGS
Many interesting results have been obtained for Au + Au reactions at AGS. The basic information about the reaction dynamics comes from the hadronic distribution. and this article reviews the recent progress of these distributions in details. The proton rapidity distribution shows significantly increased stopping compared to lighter systems, implying the formation of a state of high baryon density. Unlike reactions at this energy induced by lighter heavy ions, at low {ital m{sub t} - m{sub 0}} the proton invariant spectra deviate from a single exponential shape and become fear,. while pion spectra are found to rise in this region, with the {pi}{sup -} spectra rising faster than the {pi}{sup +} spectra. The inverse slope parameter increases faster for particles of larger mass as the number of participants in the reaction increases, an indication of increased effect of radial expansion in central collision. Anti-proton Needs have been measured recently, and unfortunately a comparison among current results from different experiments indicates discrepancy.
