Abstract (data abstract)
CERN-LHC. Prompt charged particle production in proton-proton collisions is studied with the LHCb detector at a centre-of-mass energy of $\sqrt{s}=7$ TeV in different intervals of pseudorapidity: $-2.5 < \eta < -2.0$ and $2.0 < \eta < 4.5$. Two classes of events are selected by requiring at least one track in the full forward $\eta$ range for minimum bias events and at least one track with transverse momentum greater than 1 GeV/c in $2.5 < \eta < 4.5$ for a subsample of hard QCD events. Prompt charged particles are selected imposing a limit on the sum of the ancestors life time of 10 ps so that final state particles originating in $b$ and $c$ hadron decays are considered prompt. Charged particle multiplicity distributions in $\eta$ bins and in the full forward range for the two event classes are given. Also charged particle densities as function of $\eta$ are shown in the full pseudorapidity range.
