“…Therefore, only for the simplicity of calculation we take the view of the equipartition of the energy momenta to the multiple collisions [21,22]. As a result, the desired rapidity density and the integrated multiplicity N(Y1'Y2) are expressed in the following simple formula The probability density for the equipartition distributions of the I light-like momentum fraction x% is given by…”

The energy density of the central products in the ultra-relativistic heavy ion collisions are calculated. In our estimation, the special attention is paid to the space-time extension of the emission points of the secondary hadrons which are originated in the successive nucleon-nucleon interactions within the finite size of colliding nuclei. The average collision number per produced *On leave of absence from Institute for Nuclear Study, University of Tokyo, Tanashi, Tokyo 188. iv particle, in the final state interaction. is also calculated and is used as a criterion whether the system is thermalized or not. It turns out that the attainable energy density in the central heavy ion collision is sensitive to the space-time extension of the emission points. However, if the incident energy and the mass numbers of colliding nuclei are high and large, we can get high enough energy density for the phase transition from a hadronic state to a quark-gluon plasma state.

“…There it is based on the Glauber picture of colliding tubes of nucleons, see e.g. [11,12,13,14,15,16,17]. Models of this type proceed at every step in accordance with the data available from pp and pA interactions.…”

On energy densities reached in heavy-ion collisions at the CERN SPS

We present a few estimates of energy densities reached in heavyion collisions at the CERN SPS. The estimates are based on data and models of proton-nucleus and nucleus-nucleus interactions. In all of these estimates the maximum energy density in central Pb+Pb interactions is larger than the critical energy density ε c ≈ 0.7 GeV/fm 3 following from lattice gauge theory computations. In estimates which we consider as realistic the maximum energy density is about 2ε c . In this way our analysis gives some support to claims that deconfined matter has been produced at the CERN SPS. Any definite statement requires a deeper understanding of formation times of partons and hadrons in nuclear collisions. We also compare our results with implicit energy estimates contained in earlier models of anomalous J/ψ suppression in nuclear collisions.
