Fluctuation of fluctuations in pionisation: Target excitation dependence

Abstract

This paper presents some interesting and informative results of experimental investigation on target excitation dependence of fluctuation of fluctuations studies on produced pions emitted in 16O-AgBr interactions at 60 AGeV and 32S-AgBr interactions at 200 AGeV. A search for the possible signature of chaotic behavior of multiparticle production in nucleus-nucleus collision has been performed with the help of entropy index, μq. To study the target excitation dependence of the chaotic behavior, the whole dataset is divided into subsamples having different number of recoil target protons which may be considered as a measure of target excitation.
