Abstract：
The fractal behavior of multiplicity production in 400 GeV/c pp collisions is analyzed using the modified multifractal moments. The generalized dimensions D_q, q=2-5, are calculated. A comparison with the results obtained by the method of scaled factorial moments has been made. The results show that the multifractal character is observed. The fractal analysis method proposed by Fujio Takagi has been tested.
