Abstract (data abstract)
CERN-LHC. Study of the correlations between pairs of charged particles produced in Lead-Lead collisions at a nucleon-nucleon centre-of mass energy of 2.76 TeV. The data were collected during the heavy-ion run in 2010 with over 15 million Lead-Lead events being analysed. The data were analysed using the Balance Function which describes the conditional probabilty that a particle in a momentum space P1 will be accompanied (balanced) by a particle of opposite charge and momentum P2. The user is refered to the text of the paper for the exact definition. Data are presented in terms of the relative differences in the pseudorapidities and of the azimuthal angles of the charged particles. In addition, results are given for a mixed data set from all two-particle non-same-event combinations from a few (~5) events with similar values of the z position and the reconstructed vertex and from the same centrality class and similar multiplicities.
