Abstract

This paper reports the first evidence of non-thermal phase transition in the target fragmentation of - interactions at 14.5. Factorial moment analysis has been performed in two dimensions taking into consideration the anisotropicity of the phase space. A signal of non-thermal phase transition is obtained by carrying out the investigation at that partitioning of phase space where the anisotropic scaling (self-affinity) behavior of dynamical fluctuation is best revealed. A signal of multifractality is also observed from the knowledge of anomalous fractal dimension d_q extracted from the intermittency exponent at the anisotropic phase space scenario.
