Centrality dependence of charged particle production in proton-lead collisions measured by ATLAS

Presented by Dr. Alexander MILOV

Content

The ATLAS experiment presents the first measurement observablef the centrality dependence of charged particle multiplicity and spectra measured in proton-lead collisions at sqrt(s_NN)=5.02 TeV. The data was obtained during the LHC pilot run in September 2012. The measurements are performed in a wide range of pseudorapidity covered by the ATLAS detector. Several experimental techniques are used to measure charged particle multiplicity with particle track starting from 100 MeV. Charged particle spectra and nuclear modification factor are measured for particles with the transverse momentum up to dozens of GeV. The measurements are done in several centrality classes determined by the ATLAS forward calorimeter, registering transverse energy deposition in the lead-going direction. Details of the event selection and centrality association done in the proton-lead will be also given.
