“…In Fig. 22, a compilation of pseudorapidity density data for proton+(nuclear emulsion) [178,179] and p+Pb [143] at various energies is shown, together with PHOBOS data for d+Au at √ s NN =200 GeV [138], with the centrality and normalization for the d+Au results chosen appropriately. To be more specific, the d+Au pseudorapidity densities are divided by the number of participating nucleons in the deuteron (by definition this would be unity for p+A).…”

This paper describes the conclusions that can be drawn from the data taken thus far with the PHOBOS detector at RHIC. In the most central Au+Au collisions at the highest beam energy, evidence is found for the formation of a very high energy density system whose description in terms of simple hadronic degrees of freedom is inappropriate. Furthermore, the constituents of this novel system are found to undergo a significant level of interaction. The properties of particle production at RHIC energies are shown to follow a number of simple scaling behaviors, some of which continue trends found at lower energies or in simpler systems. As a function of centrality, the total number of charged particles scales with the number of participating nucleons. When comparing Au+Au at different centralities, the dependence of the yield on the number of participants at higher p T (∼4 GeV/c) is very similar to that at low transverse momentum. The measured values of charged particle pseudorapidity density and elliptic flow were found to be independent of energy over a broad range of pseudorapidities when effectively viewed in the rest frame of one of the colliding nuclei, a property we describe as "extended longitudinal scaling". Finally, the centrality and energy dependences of several observables were found to factorize to a surprising degree.

“…The investigation of particle-nucleus collisions is fundamental for understanding the nature of the interaction process and these collisions have been studied extensively [1][2][3][4][5][6]. In experiments on hadron-nucleus (hA) collisions, mostly the attention was paid to the studies of relativistic charged particles produced during these reactions; however, less attempt was made to study the grey and black particles.…”

We report some results on the compound multiplicity distribution at 340 GeV/c − nucleus interactions. Compound multiplicity distribution is found to depend on the target size and the distribution becomes broader. The peak of the distribution shifts towards higher values of the compound particle multiplicity. Mean compound multiplicity is found to vary linearly with grey, heavy, and shower particle multiplicity. Correlations between different particle multiplicities have been studied in detail. Dispersion of compound multiplicity distributions and its ratio with the mean value is observed to obey a linear relationship with different particle multiplicities except for shower particles where dispersion is almost independent of shower particles. Mean normalized multiplicity has also been studied in terms of created charged particles.

“…Anzon [2] et al have also used the same function as given by Slattery [22] but with different values of the parameters for pion-nucleus interactions at 200 GeV. The values of the fitted parameters in the functional form appear as (z)= (3.0z + 26.0z 3 + 4.6z 5 + 0.18z 7 ) exp (-4.0z) (8) El-Nadi et al [3] have also tested KNO scaling in pion-nucleus interactions using the function given by Buras et al [24].…”

“…During the last many years, the work on high energy experiments was carried out by several workers [1][2][3][4][5][6][7][8] mostly for shower particles which are fast moving charged particles or we can say that relativistic charged particles in hadron-nucleus (hA) and nucleus-nucleus (AA) collisions. The investigation of hA collisions is fundamental for understanding the nature of the interaction process.…”
