SQUEEZE-OUT OF PION EMISSION IN RELATIVISTIC HEAVY-ION COLLISIONS

The azimuthal angle distributions of charged pions with respect to the reaction plane determined by projectile heavy fragments is presented for 32S at 200A GeV. The squeezeout of pions perpendicular to the reaction plane for 28Si at 14.5A GeV and 197Au at 10.6A GeV is observed as a function of impact parameter (b) and the target mass.
