Pronounced Fluctuations of Target Fragments in ForwardHemisphere Only in Ultra Relativistic Nuclear Collision

Abstract

Dynamical fluctuation of target evaporated black particles isinvestigated in both forward and backward hemispheres within theframework of multi-dimensional factorial moment methodology using thebrilliant concept of the Hurst exponent. We analyse the black particlesemitted in 32S–AgBr interactions at 200 AGeV and it isevident that the dynamical fluctuation in the backward hemisphere isself-affine. In the forward hemisphere, dynamical fluctuation isself-similar but not self-affine. However, study indicates that thefluctuation in the forward hemisphere is more pronounced than that inbackward hemisphere.
