abstract = {We present the charged-particle pseudorapidity density in
Pb–Pb collisions at sNN=5.02 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
$(0–5\%)$ collisions we find 21400±1300 , while for the
most peripheral $(80–90\%)$ we find 230±38 . This
corresponds to an increase of $(27±4)\%$ over the results
at sNN=2.76 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
pseudorapidity 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.},
