Abstract (data abstract)
CERN-LHC. Measurement of the charged particle mulitplicity and its depenedence on pseudorapidity and transverse momentum in P P collisions at a centre-of-mass energy of 900 GeV. The data were taken during the period December 2009 with an approximate total integrated luminosity of 9 mub-1 and cover the pseudorapidity range -2.5 to 2.5 with charged particle transverse momenta > 0.5 GeV. Numerical values supplied by G. Brandt.
