Is there flow at the AGS?

PDF Version Also Available for Download.

Description

We have employed the nearly 4{pi}-calorimetric coverage of the E877 apparatus in order to determine flow in different regions of pseudo-rapidity from the measured transverse energy in Au+Au collisions at 11.4 A{center_dot}GeV/c. Signatures for the side-splash in the reaction plane at forward and backward rapidities have been established. Indications of a non-zero eccentricity of particles in the reaction plane at mid-rapidity are also found. These observations complement analyses deriving collective longitudinal motion from dN/dy-spectra of protons, kaons, and pions as well as collective transverse motion of the same particles from m{sub t}-spectra at midrapidity.
