Figure 2

Charged-particle pseudorapidity density in the central pseudorapidity region |$\eta$| < 0.5 for inelastic and non-single-diffractive collisions [4,16-25], and in |$\eta$| < 1 for inelastic collisions with at least one charged particle in that region (INEL$>$0$_{|\eta|< 1}$), as a function of the centre-of-mass energy. The lines indicate thefit using a power-law dependence on energy. Note that data points at the same energy have been slightly shifted horizontally for visibility.
