摘要：

We compute in QCD perturbation theory the transverse energy carried by gluons, quarks and antiquarks with P(T) greater-than-or-equal-to P0 almost-equal-to 2 GeV in Pb+Pb collisions at square-root s = 5500A GeV by using structure functions compatible with the small-x increase observed at HERA. This gives a perturbative estimate for the energy and entropy density of the bulk system at times tau approximately 0.1 fm. The predicted initial gluon entropy density gives a lower limit of about 2200... 3400 for the final charged multiplicity. Sources of further entropy increase are discussed.
