Measurement of Charged Particle Production in p-p Collisions at LHC — •Gerhard Brandt — Deutsches Elektronen-Synchrotron

In late November 2009 the LHC produced first proton-proton collisions at a centre-of-mass energy of √s=900 GeV. Before Christmas 2009 a statistically meaningful sample of events was recorded by the experiments. An essential early measurement possible with these data is the analysis of minimum bias events. They can be used to understand the detectors and confirm results from from earlier experiments. This talk gives an overview over the analysis within the ATLAS collaboration. First results on charged particle production in inelastic minimum bias events at LHC are shown.
