The measurements of charged-particle multiplicity and transverse energy at
mid-rapidity in Pb-Pb collisions at sqrt(sNN) = 2.76 TeV are reported as a
function of centrality. The fraction of the inelastic cross section recorded by
the ALICE detector is estimated using a Glauber model. The results scaled by
the number of participating nucleons are compared with pp collisions at the
same collision energy, to similar results obtained at significantly lower
energies, and with models based on different mechanisms for particle production
in nuclear collisions.Comment: Contribution to QM 201
