System size and centrality dependence of the balance function in A+A
collisions at root S-NN=17.2 GeV

Αγγλικά

Electric charge correlations were studied for p+p, C+C, Si+Si, and
centrality selected Pb+Pb collisions at root s(NN) = 17.2 GeV with the
NA49 large acceptance detector at the CERN SPS. In particular,
long-range pseudorapidity correlations of oppositely charged particles
were measured using the balance function method. The width of the
balance function decreases with increasing system size and centrality of
the reactions. This decrease could be related to an increasing delay of
hadronization in central Pb+Pb collisions.
