| Abstract: | Energy density for the central region in relativistic heavy ion collisionscan be estimated via the pseudora-pidity distribution of transverse energy. The way to estimate the local energy density for the centralregion in relativisticheavyion collisions is proposed, in which only final state particles emitted from the same source are included. Thcarrived energy density in NA49 experiments is about 1.03 GeV/fm3. |
