Abstract The multiplicity difference correlators between two well-separated bins are studied in second-order quark-gluon plasma (QGP) phase transition within the Ginzburg-Landau model. For the case with very low mean multiplicities, an exponent γ is found, which has very weak dependence on the parameters of the model and can be used as a signal for the formation of QGP in ultra-relativistic heavy-ion collisions.
