Abstract (data abstract)
CERN-LHC. Measurement of charged particle distributions in proton-proton collisions at centre-of-mass energies of 0.9 and 7 TeV. The data are collected with a minimum-bias trigger and are divided into three regions according to the azimuthal angular difference of the charged particle from the direction of the leading track. Toward is < 60 degrees, Away is > 120 degrees and Transverse is between 60 and 120 degrees. In each of these regions the charged particle multiplicity, PT density and average PT are measured.
