Event shapes for Au + Au collisions at 11. 4 GeV/c per nucleon were studied over nearly the full solid angle with the E877 apparatus. The analysis was performed by Fourier expansion of azimuthal distributions of the transverse energy (Eₓ) measured in different pseudorapidity intervals. For semicentral collisions a pronounced event anisotropy is identified with a clear forward-backward anticorrelation. In the forward pseudorapidity interval up to 9% of the Eₓ is in a directed component. The signal decreases for peripheral and very central collisions.
Barrette et al. (Mon,) studied this question.
