We present the charged-particle pseudorapidity density in Pb-Pb collisions at $\\sqrt{s_{_{\\mathrm{NN}}}}=5.02\\,\\mathrm{TeV}$ in centrality classes measured by ALICE.  The measurement covers a wide pseudorapidity range from $-3.5$ to $5$, which is sufficient for reliable estimates of the total number of charged particles produced in the collisions.  For the most central collisions we find $21\\,400\\pm 1\\,300$ while for the most peripheral we find $230\\pm 38$. This corresponds to an increase of $(27\\pm4)\\%$ over the results at $\\sqrt{s_{_{\\mathrm{NN}}}}=2.76\\,\\mathrm{TeV}$ previously reported by ALICE.  The energy dependence of the total number of charged particles produced in heavy-ion collisions is found to obey a modified power-law like behaviour.  The charged-particle\npseudorapidity density of the most central collisions is compared to model calculations - none of which fully describes the measured distribution. We also present an estimate of the rapidity density of charged particles. The width of that distribution is found to exhibit a remarkable proportionality to the beam rapidity, independent of the collision energy from the top SPS to LHC energies.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.78365.v1/t1","@type":"Dataset","description":"Charged-particle pseudorapidity density for ten centrality classes over a broad $\\eta$ range in Pb-Pb collisions at $\\sqrt{s_{_{\\mathrm{NN}}}}=5.02\\,\\mathrm{TeV}$.
