Is There Flow at the Ags ?
نویسنده
چکیده
We have employed the nearly 4;r-calorimetric coverage of the E877 apparatus in order to determine flow in different regions of pseuderapidity from the measured t r ans verse energy in Au+Au collisions at 11.4 A.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 mt-spectra at midrapidity.
