“…In spite of this fact limiting fragmentation is found to remain valid over a wide range of energy. This asymptotic property has been observed experimentally in a variety of collision processes such as hadron-hadron, 29,196 hadron-nucleus, 29,197 and nucleus-nucleus 120,124,125,153,[198][199][200][201][202][203][204][205][206] for produced charged hadrons in fragmentation region at different energies. It can be clearly observed that this scaling fea-ture covers a more extended range of η than expected according to the original hypothesis of limiting fragmentation due to which the term extended longitudinal scaling is often used to describe this phenomenon.…”

“…15 and 16, the intermittent behaviour of charged hadrons produced in the nucleus-nucleus interactions are shown in rapidity-and azimuthal-space. 153 The slope (φ q )in a plot of lnF q vs -lnδy at a given positive integer q is called intermittency index or intermittency slope which provide us an opportunity to characterize the apparently irregular fluctuations of the particle density. The term intermittency was chosen in analogy to the intermittent temporal and spatial fluctuations If there is no dynamical contribution to the multiplicity fluctuation, such as due to a phase transition or any other type of mechanism, P n should exhibit the Poisson distribution, reflecting only the statistical fluctuations.…”

The present article reviews facts and problems concerning charge hadron production in high energy collisions. Main emphasis is laid on the qualitative and quantitative description of general characteristics and properties observed for charged hadrons produced in such high energy collisions. Various features of available experimental data e.g., the variations of charged hadron multiplicity and pseudo-rapidity density with the mass number of colliding nuclei, center-of-mass energies and the collision centrality obtained from heavy-ion collider experiments are interpreted in the context of various theoretical concepts and their implications. Finally, several important scaling features observed in the measurements mainly at RHIC and LHC experiments are highlighted in the view of these models to draw some insight regarding the particle production mechanism in heavy-ion collisions.

A detailed study on the multiplicity characteristics of the slow target fragments emitted in relativistic heavy-ion collisions has been carried out at E Lab = 3.7 A and 200A GeV using 32 S projectile. The beam energy dependence of the black particles produced in the full phase space of 32 S -emulsion (32 S -Em) interactions on the target size in terms of their moments (mean, variance, skewness and kurtosis) is investigated. The various order moments of target fragments emitted in the interactions of 32 S beams with the heavy ( AgBr ) target nuclei are estimated in the forward (FHS) and backward (BHS) hemispheres. The investigated values of ratio of variance to mean at both energies show that the multiplicity distributions (MDs) are not Poissonian and the strongly correlated emission of target fragments are in the forward directions. The degree of anisotropic fragment emission and nature of correlation among the emitted fragments are investigated. The energy dependence of entropy is examined in both hemispheres. The entropy values normalized to average multiplicity are found to be energy independent. Scaling of MD of black particles produced in these interactions has been studied to verify the validity of scaling hypothesis via two scaling (Koba–Nielsen–Olesen (KNO)-scaling and Hegyi-scaling) functions. A simplified universal function has been used in each scaling to display the experimental data.
