Balance functions in coalescence model

Abstract

It is shown that the quark-antiquark coalescence mechanism for pion production allows to explain the small width of the balance function observed for central collisions of heavy ions, provided effects of the finite acceptance region and of the transverse flow are taken into account. In contrast, the standard hadronic cluster model is not compatible with this data.
