Charged particle multiplicity fluctuations in simulated pp collisions at have been studied by the method of scaled factorial moment for the minimum bias events generated by Ultra-Relativistic Quantum Molecular Dynamics (UrQMD) model in the pseudo-rapidity , azimuthal angle () and two-dimensional anisotropic phase space. Strong intermittent types of fluctuations have been observed for the UrQMD simulated data. Systematic studies of intermittent fluctuations in terms of scaled factorial moments have been utilized to extract the anomalous fractal dimension in the pseudo-rapidity , azimuthal angle () and two-dimensional anisotropic phase space. Search for the quark-hadron phase transition in the framework of Ginzburg–Landau theory of the second-order phase transition in the light of the scaled factorial moment method has also been performed.
