Hadronic multiplicity distribution and dynamical fluctuations under QGP phase transitions
【摘要】：正 Hadronic multiplicity distributions in small bins are studied within the Ginzburg-Landau description for quark-hadron phase transitions. Direct comparison of the distributions with Poisson ones (with the same averages) is made in the light of dynamical factors d_q for the distributions and ratios D_q≡d_q/d_1. Scaling behavior between D_q' s is found, which can be used to detect the formation of quark-gluon plasma. The same method can be used in the analysis of other processes without phase transition.
