ATLAS first results Charged-particle multiplicities in pp interactions at sqrt(s) = 900 GeV

The first physics results from $pp$ collisions measured with the ATLAS detector at the Large Hadron Collider (LHC) are presented. The analysis within the kinematic range pT > 500 MeV, eta < 2.5, and at least one charged particle in this range, is summarised. The charged-particle multiplicity p...

description The first physics results from $pp$ collisions measured with the ATLAS detector at the Large Hadron Collider (LHC) are presented. The analysis within the kinematic range pT > 500 MeV, eta < 2.5, and at least one charged particle in this range, is summarised. The charged-particle multiplicity per event and unit of pseudorapidity at eta = 0 is measured to be 1.333 +/- 0.003(stat.) +/- 0.040(syst.), which is 5-15% higher than the Monte Carlo model predictions.
