“…One possible explanation of the differences is that the corrections for the CMS calorimetry measurement are determined by Monte Carlo [30], while the corrections for the ALICE measurement are mainly data driven. PHENIX [28] reported that while dE T /dη scaled by N part has a pronounced centrality dependence, as seen in Fig. 8, dE T /dη scaled by the number of constituent quarks, N quark , dE T /dη / N quark /2 shows little centrality dependence within the systematic uncertainties for collisions at √ s NN = 62.4-200 GeV.…”

“…[58] and assuming each participating nucleon has an effective transverse radius of R = (σ inel NN /4π ) 1/2 = 0.71 fm results in A = 162.5 fm 2 for central collisions (b = 0 fm). This is equivalent to a transverse overlap radius of R = 7.19 fm, which is close to the value of 7.17 fm often used in estimates of energy densities using a Woods-Saxon distribution to determine the effective area [28,64]. The centrality dependence of A is obtained by assuming it scales as (σ Fig.…”

“…The centrality dependence of A is obtained by assuming it scales as (σ Fig. 14 for R = 7.17 fm, the same value of R used by PHENIX at RHIC energies [28,64]. In addition to estimating the volume-averaged energy density, it is also interesting to estimate the energy density attained at the core of the collision area.…”

We report the transverse energy (E T ) measured with ALICE at midrapidity in Pb-Pb collisions at √ s NN = 2.76 TeV as a function of centrality. The transverse energy was measured using identified single-particle tracks. The measurement was cross checked using the electromagnetic calorimeters and the transverse momentum distributions of identified particles previously reported by ALICE. The results are compared to theoretical models as well as to results from other experiments. The mean E T per unit pseudorapidity (η), dE T /dη , in 0%-5% central collisions is 1737 ± 6(stat.) ± 97(sys.) GeV. We find a similar centrality dependence of the shape of dE T /dη as a function of the number of participating nucleons to that seen at lower energies. The growth in dE T /dη at the LHC energies exceeds extrapolations of low-energy data. We observe a nearly linear scaling of dE T /dη with the number of quark participants. With the canonical assumption of a 1 fm/c formation time, we estimate that the energy density in 0%-5% central Pb-Pb collisions at √ s NN = 2.76 TeV is 12.3 ± 1.0 GeV/fm 3 and that the energy density at the most central 80 fm 2 of the collision is at least 21.5 ± 1.7 GeV/fm 3 . This is roughly 2.3 times that observed in 0%-5% central Au-Au collisions at √ s NN = 200 GeV.

The nucleus-nucleus impact parameter and collision geometry of a heavy ion collision are typically characterized by assigning a collision "centrality". In all present heavy ion experiments centrality is measured indirectly, by detecting the number of particles or the energy of the particles produced in the interactions, typically at high rapidity. Centrality parameters are associated to the measured detector response using the Glauber model. This approach suffers from systematic uncertainties related to the assumptions about the particle production mechanism and limitations of the Glauber model. In the collider based experiments there is a unique possibility to measure centrality parameters by registering spectator fragments remaining from the collision. This approach does not require model assumptions and relies on the fact that spectators and participants are related via the total number of nucleons in the colliding species. This article describes the concept of a centrality detector for heavy ion experiment, which measures the total mass number of all fragments by measuring their deflection in the magnetic field of the collider elements.
