The multiplicity distribution in $\eta$ bins (shown as points with statistical error bars) with predictions of different event generators. The inner error bar represents the statistical uncertainty and the outer error bar represents the systematic and statistical uncertainty on the measurements. The data in both figures are identical with predictions from Pythia 6, Phojet and Pythia 8 in (a) and predictions of the Pythia 6 Perugia tunes with and without diffraction in (b).

The multiplicity distribution in the forward $\eta$ range (shown as points with error bars) with predictions of different event generators. The shaded bands represent the total uncertainty on the measurements. The data in both figures are identical with predictions from Pythia 6, Phojet and Pythia 8 in (a) and predictions of the Pythia 6 Perugia tunes with and without diffraction in (b).

The KNO distributions in different bins of $\eta$. Only the the statistical uncertainties are shown.

The charged particle densities as a function of $\eta$ (shown as points with statistical error bars) and comparisons with predictions of event generators, as indicated in the key. The shaded bands represent the total uncertainty. The events are selected by requiring at least one charged particle in the range $2.0<\eta<4.5$. The data in both figures are identical with predictions from Pythia 6, Phojet and Pythia 8 in (a) and predictions of the Pythia 6 Perugia tunes with and without diffraction in (b).

The multiplicity distribution in $\eta$ bins (shown as points with error bars) with predictions of different event generators. The inner error bar represents the statistical uncertainty and the outer error bar represents the systematic and statistical uncertainty on the measurements. The events have at least one track with a $ p_{\rm T} >1.0$ $ {\mathrm{ Ge V /}c}$ in the pseudorapidity range $2.5 < \eta < 4.5$. The data in both figures are identical with predictions from Pythia 6, Phojet and Pythia 8 in (a) and predictions of the Pythia 6 Perugia tunes in (b).
