Description
The ATLAS experiment has studied the centrality dependence of global event characteristics in proton-lead collisions at sqrt(s_NN)=5.02 TeV. A total integrated luminosity of 30nb-1 was collected during LHC proton-lead runs in the fall and winter of 2012-13. The centrality of proton-lead collisions was characterized using the total transverse energy measured in the ATLAS forward calorimeter on the Pb-going side of the detector. Results will be presented for measurements of charged particle pseudo-rapidity and transverse momentum spectra measured over a wide pseudo-rapidity range
(|eta| < 2.5) covered by the ATLAS inner detector. That wide pseudorapidity coverage also allows the study of long-range particle correlations. Results of two and multi-particle correlation measurements in p+Pb collisions using different analysis techniques will be presented in the talk.
