Angular correlations between charged particles from proton-proton collisions at √s = 900 GeV and √s = 7 TeV measured with the ATLAS detector
2010 (English)Conference paper (Other academic)
This note describes a study of angular correlations between charged primary particles stemming from proton-proton collisions at the Large Hadron Collider. Two observables are defined based on ∆φ, the angle in the transverse plane between the particle with the highest transverse momentum and any other particle in the collision. The shapes of the observables have a very small systematic uncertainty and are different for √s = 900 GeV and 7 TeV. The distributions observed in data are compared to different tunes of the PYTHIA event generator.
