Charged-particle multiplicity density at midrapidity in central Pb-Pb collisions at s_NN=2.76??TeV
Original language description
The first measurement of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at a center-of-mass energy per nucleon pair s_NN=2.76??TeV is presented. For an event sample corresponding to the most central 5% of the hadronic crosssection, the pseudorapidity density of primary charged particles at midrapidity is 15844(stat)76(syst), which corresponds to 8.30.4(syst) per participating nucleon pair. This represents an increase of about a factor 1.9 relative to pp collisions at similar collision energies, and about a factor 2.2 to central Au-Au collisions at sNN=0.2??TeV. This measurement provides the first experimental constraint for models of nucleus-nucleus collisions at LHC energies.
