【 摘 要 】

We report measurements of two-particle charge-dependent correlations in pp, p- Pb, and Pb-Pb collisions at √ sNN = 7, 5.02, and 2.76 TeV, respectively, as a function of pseudorapidity and azimuthal angle differences. These measurements, carried out using the balance function, probe the charge creation time and the development of collectivity in the produced systems. The balance function is studied as a function of the event multiplicity as well as the transverse momentum (pT) of charged particles detected in the range n
