SELF-AFFINE SCALING AND NON-THERMAL PHASE TRANSITION IN TARGET FRAGMENTS OF MUON–NUCLEUS INTERACTIONS AT HIGH ENERGY.

In this paper non-thermal phase transition for the target fragments of lepton–nucleus interactions at (420±45) GeV is studied in the framework of two-dimensional factorial moment methodology using the concept of Hurst exponent (H) to take care of anisotropic phase space. An indication of non-thermal phase transition is obtained where the anisotropic scaling behavior (self affinity) of dynamical fluctuation is best revealed (H = 0.8). [ABSTRACT FROM AUTHOR]
