Evidence of self-affine multiplicity fluctuation of target residues in 84Kr-AgBr interactions at 1.7 AGeV

    Corresponding author: ZHANG Dong-Hai,

Abstract: 

Self-affine multiplicity scaling is investigated in the framework of a two-dimensional factorial moment methodology using the concept of the Hurst exponent (H). Analyzing the experimental data of target evaporated fragments
emitted in 84Kr-AgBr interactions at 1.7 AGeV revealed that the best power law behavior is exhibited for H=0.3 indicating a self-affine multiplicity fluctuation pattern. A signal of multifractality is also observed from knowledge of the anomalous fractal dimension dq extracted from the intermittency exponent aq of the anisotropic phase space scenario.
