dc.description.abstractIn ultrarelativistic heavy-ion collisions, correlations of particles with opposite quantum numbers provide insight into quark production mechanisms and time scales, collective motion, and re-scattering in the hadronic phase. The longitudinal and azimuthal widths of balance functions for charged kaons and charged pions are used to examine the two-wave quark production model proposed to explain quark-antiquark production within the QGP, which predicts a large increase in up and down quark pairs relative to strange quark pairs around the time of hadronization. Balance functions are also analyzed in small collision systems such as p-Pb and pp to study fragmentation effects and possible collective effects in high-multiplicity events. A comprehensive set of balance functions has been measured using the ALICE detector, including results for unidentified hadrons in Pb-Pb and p-Pb collisions at root s(NN) = 5.02 TeV, for charged pions in Pb-Pb collisions at root s(NN) = 2.76 TeV, p-Pb collisions at root s(NN) = 5.02 TeV and pp collisions at root s = 7 TeV, and for charged kaons in Pb-Pb collisions at root s(NN) = 2.76 TeV. The first balance function yield results are also presented.
