Studies of charged particle correlations and underlying events with the ATLAS detector

The ATLAS experiment has recorded significant amounts of minimum bias events at center of mass energies of 900 GeV and 7 TeV at the LHC. We report on the first ATLAS underlying event studies. The charged particle density and the sum and average charged transverse momentum are measured as a function...

Sumario:The ATLAS experiment has recorded significant amounts of minimum bias events at center of mass energies of 900 GeV and 7 TeV at the LHC. We report on the first ATLAS underlying event studies. The charged particle density and the sum and average charged transverse momentum are measured as a function of the leading track transverse momentum. The angular distribution of the charged tracks and their transverse momentum with respect to the leading track is also presented. We also report on studies of angular correlations of charged particle tracks in the transverse plane and in pseudorapidity.
