Abstract:
Abstract: We present a measurement of two-particle angular correlations in proton proton collisions at ps = 900 GeV and 7TeV. The collision events were collected during 2009 and 2010 with the ATLAS detector at the Large Hadron Collider using a single-arm
minimum bias trigger. Correlations are measured for charged particles produced in the kinematic range of transverse momentum pT > 100MeV and pseudorapidity jj < 2.5.
A complex structure in pseudorapidity and azimuth is observed at both collision energies. Results are compared to pythia 8 and herwig++ as well as to the AMBT2B, DW and Perugia 2011 tunes of pythia 6. The data are not satisfactorily described by
any of these models.
