FLOW AT BROOKHAVEN AGS ENERGY (11.6 GEV NUCLEON) - A BAROMETER FOR HIGH-DENSITY EFFECTS/

Preliminary data on transverse energy ''flow'' and event asymmetries r eported by the E877(814) Collaborations are compared to ARC (a relativ istic cascade) model calculations for Au + Au at full AGS Brookhaven ( Alternating Gradient Synchroton) beam energy. ARC triple differential cross sections for protons and pions are presented. Proton flow is pro duced in ARC, with the maximum (P-x)similar to 120 MeV/c. For central events [P-x] for the pions is near zero, consistent with experiment. T he comparison with data provides a constraint on the size of flow at t he highest energy available, to be put beside that at Bevalac energy. This sets the stage for examining flow at intermediate energies, now b eing measured by E895, for signs of baryon rich plasma.
