Charged Particle Multiplicity and Pseudorapidity Density Measurements in pp collisions with ALICE at the LHC

Abstract

These proceedings describe the charged-particle pseudorapidity densities and multiplicity distributions measured by the ALICE detector in pp collisions at $\sqrt{s}=0.9$ and 7 TeV in specific phase space regions. The pseudorapidity range $|\eta |<0.8$, together with $p_{\mathrm{T}}$ cuts at 0.15, 0.5 and 1 GeV/$c$ is considered. The classes of events considered are those having at least one charged particle in the kinematical ranges just described. The results obtained by ALICE are compared to Monte Carlo predictions.
