Multiplicity Fluctuation at Second-order Phase Transition in QGP on the Base of Squeezed States

Nonlin.Phenom.Complex Syst.5:281-288,2002 We use the generalized squeezed state description in the framework of the Ginzburg-Landau theory. Multiplicity distributions of the squeezed states are studied at second-order phase transition at different squeeze factors. It is shown that the normalized factorial moments exhibit a specific behaviour as functions of the resolution scale. We obtain the values of the scaling exponent which coincides with experimental data at small squeeze factor.
