| Abstract: | The non-thermal phase transition in high energy collisions is studied in detail in the framework of random cascade model.
The relation between the characteristic parameter Ap, of phase transition and the rank q of moment is obtained using Monte Carlo simulation, and the existence of two phases in
self-similar cascading multiparticle systems is shown. The relation between the critical point qc of phase transition on the
fluctuation parameter a is obtained and compared with the experimental results from NA22. The same study is carried out also
by analytical calculation under central limit approximation. The range of validity of the central limit approximation is discussed. |
