Global Transverse Energy-Distributions In Si+Al, Au At 14.6a Gev/C And Au+Au At 11.6a Gev/C

Measurements of the global transverse energy distributions dsigma/dE(T) and dE(T)/deta using the new AGS beam of Au-197 at 11.6A GeV/c on a Au target, as well as a beam of Si-28 at 14.6A GeV/c on Al and Au targets, are presented for a lead-glass detector with acceptance 1.3 less-than-or-equal-to eta less-than-or-equal-to 2.4 and 0 less-than-or-equal-to phi < 2pi. The dsigma/dE(T) 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 dsigma/dE(T) 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.
