Abstract
Self-affine multiplicity scaling is investigated in the framework of
two-dimensional factorial moment methodology using the concept of the Hurst
exponent (
H). Our investigation on experimental data of the target-evaporated slow particles emitted in
32S-AgBr interactions at 200
AGeV and
28Si-AgBr interactions at 14.5 AGeV reveals that a better
power law behavior is exhibited in self-affine analysis than self-similar
analysis. This work shows a clear evidence of self-affine target
fragmentation.
