Correction to Bjorken Energy Density Calculations for Central A-A Collisions

Abstract

We present geometry-based corrections to estimates of the Bjorken energy density in a broad range of heavy-ion collision energies (from RHIC to the LHC) considereing non-circular shape of the nuclei overlap area in case of events selected in 0-5% centrality classes. We compare the updated Bjorken energy excitation function, obtained in our study for these very central A-A collisions, to the previously obtained ones. We present also and discuss the relevant energy dependences of pion, kaon and proton contributions to the Bjorken energy density that are also estimated in our study.
