We propose a forward-backward multiplicity correlation function C N FB which is experimentally accessible, to measure the non-collectivity contribution. It is found that the function is sensitive to both the jet contribution and small number statistics. We point out that the effect of the latter is also involved in the previous studies of the forward-backward elliptic correlation function but was misinterpreted as a contribution from jets. We study the C N FB in Au+Au collision at GeV with a multiphase transport model (AMPT). The result shows t...
