Abstract

Measurements of the global transverse energy distributions dσ/dET and dET/dη using the new AGS beam of 197Au at 11.6A GeV/c on a Au target, as well as a beam of 28Si at 14.6A GeV/c on Al and Au targets, are presented for a leadglass detector with acceptance 1.3 ≤ η ≤ 2.4 and 0 ≤ φ < 2π. The dσ/dET spectra are observed to have different shapes for the different systems and simple energy rescaling does not account for the projectile dependence. The Au+Au dσ/dET spectrum is satisfactorily constructed from the upper edge of Si+Au by the geometric Wounded Projectile Nucleon Model after applying a correction for the beam energy.
