Within the extended Ginzburg–Landau model, multiplicity difference correlators in first-order quark–gluon plasma phase transition are investigated for two well-separated bins with nonidentical mean multiplicities. For very small bin width, a kind of scaling behavior and a universal exponent index γ, which are independent of the parameters of model, are found.

Abstract We elaborate a theory of giant vortices [1] based on an asymptotic expansion in inverse powers of their winding number n. The theory is applied to the analysis of vortex solutions in the abelian Higgs (Ginzburg-Landau) model. Specific properties of the giant vortices for charged and neutral scalar fields as well as different integrable limits of the scalar self-coupling are discussed. Asymptotic results and the finite-n corrections to the vortex solutions are derived in analytic form and the convergence region of the expansion is determined.
