Abstract
The first physics results from pp collisions measured with the ATLAS detector [1] at the Large Hadron Collider (LHC) [2] are presented. The analysis within the kinematic range pT > 500 MeV, |η| < 2.5, and at least one charged-particle in this range, is summarised. The charged-particle multiplicity per event and unit of pseudorapidity at η = 0 is measured to be 1.333±0.003(stat.)±0.040(syst.), which is 5–15% higher than the Monte Carlo model predictions.
