【Abstract】 The pseudorapidity distribution for charged prides Produced in PP collisions at 400GeV/c has been measured by using the LEBC films offered by the CERN NA27 collaboration. The fastorial moments up to q=7 have been calculated by star integer method. The analytic results indicate that a non-thermal phase transition and two different regimes of multiparticle production may exist. The multifractal structure of the fluctuation has been observed supporting the random cascade model of particle production.更多还原
