Abstract
Forward-backward multiplicity correlations have been measured with the STAR detector for Au + Au, Cu + Cu and p + p collisions at root(NN)-N-S = 200 GeV. A strong, long-range correlation is observed for central heavy-ion collisions that vanishes in semi-peripheral events and p + p collisions. Both the dual parton model and the color glass condensate indicate that long-range correlations are due to multiple parton interactions. This suggests that dense partonic matter might have been created in mid-central and central Au + Au collisions at root S-NN = 200 GeV.
