Multiplicity Distributions in Pseudorapidity Intervals With $^{32}$S at 200-{GeV}/nucleon and $^{16}$O at 200-{GeV}/nucleon and 60-{GeV}/nucleon

Singh, G. ; Sengupta, K. ; Jain, P.L. ;
Phys.Rev.Lett. 61 (1988) 1073, 1988.
Inspire Record 24235 DOI 10.17182/hepdata.20129

We present results of our systematic studies of charged-shower-particle multiplicities and their dependence on pseudorapidity intervals for nearly central events produced by S32 at 200 GeV/nucleon and O16 at 200 and 60 GeV/nucleon in nuclear emulsion. An increase in the particle density with the increase of particle energy and mass is observed. We find an energy-independent linear relation between the maximum particle density (in a given pseudorapidity interval) and shower-particle multiplicity.

Limiting Fragmentation in Oxygen Induced Emulsion Interactions at 14.6-a/{GeV}, 60-a/{GeV} and 200-a/{GeV}

The EMU01 collaboration Adamovich, M.I. ; Aggarwal, M.M. ; Arora, R. ; et al.
Phys.Rev.Lett. 62 (1989) 2801, 1989.
Inspire Record 268021 DOI 10.17182/hepdata.20041

Pseudorapidity distributions of relativistic singly charged particles in oxygen-induced emulsion interactions at 14.6, 60, and 200 GeV/nucleon are studied. Limiting fragmentation behavior is observed in both the target and projectile fragmentation regions for a central as well as for a minimum-bias sample. Comparisons with the fritiof model reveal that the picture of fragmenting strings successfully describes the observed data.

Multiplicities of secondaries in interactions of 1.8-GeV/nucleon Fe-56 nuclei with photoemulsion and the cascade evaporation model

Dudkin, V.E. ; Kovalev, E.E. ; Nefedov, N.A. ; et al.
Nucl.Phys.A 509 (1990) 783-799, 1990.
Inspire Record 302290 DOI 10.17182/hepdata.36888

A nuclear photographic emulsion method was used to study the charge-state, ionization, and angular characteristics of secondaries produced in inelastic interactions of 56 Fe nuclei at 1.8 GeV/nucleon with H, CNO, and AgBr nuclei. The data obtained are compared with the results of calculations made in terms of the Dubna version of the cascade evaporation model (DCM). The DCM has been shown to satisfactorily describe most of the interaction characteristics for two nuclei in the studied reactions. At the same time, quantitative differences are observed in some cases.

Mod.Phys.Lett.A 6 (1991) 29-39, 1991.

We report the multiplicity and angular distributions of the low energy target-associated particles from 32S and 16O induced reactions at 200 GeV/nucleon and 16O induced reactions at 60 GeV/nucleon in emulsion. The results are compared with the Monte-Carlo Code VENUS.

On the production of fast and slow particles in nucleus-nucleus collisions at ultrarelativistic energies

Jain, P.L. ; Sengupta, K. ; Singh, G. ;
Phys.Rev.C 44 (1991) 844-853, 1991.
Inspire Record 315632 DOI 10.17182/hepdata.26111

Multiplicity and angular distributions of shower, grey, and black particles produced in the interactions of S32 at 200A GeV, O16 at 200 and 60A GeV, and He4 at ∼140A GeV in emulsion are compared with the predictions of a Monte Carlo code which takes into account the internuclear cascading. The correlations between the various parameters belonging to the same or to the different kinds of particles are discussed. The data on shower and grey particles from all the beams are well described by the code. However, the black prong data show a significant departure from this model.

Intranuclear cascading at ultrahigh-energy in heavy ion interactions

Jain, P.L. ; Singh, G. ; Sengupta, K. ;
Z.Phys.C 52 (1991) 465-470, 1991.
Inspire Record 316804 DOI 10.17182/hepdata.14775

Intranuclear cascading mechanism one of the important non-linear effects in high energy nucleusnucleus collisions is investigated. The data on multiplicity (ns) and pseudorapidity (η) distributions of shower particles produced by32S and16O at 200A GeV,16O at 60A GeV,28Si at 14.5A GeV and He at ≈140A GeV are presented and compared with the string model VENUS, which takes into account the cascade interactions of secondary particles. The effect of the intranuclear collisions on the distributions of <η> versus <ns> is discussed for all the beams.

Particle production in interactions of 200-GeV/nucleon oxygen and sulfur nuclei in nuclear emulsion

The KLM collaboration Dabrowska, A. ; Holynski, R. ; Jurak, A. ; et al.

Inspire Record 338512 DOI 10.17182/hepdata.40446

Oxygen and sulfur nuclei with energies of 200 GeV/nucleon have been allowed to interact in nuclear emulsions exposed at CERN. These emulsions have been scanned with a minimum bias so that essentially all the interactions occurring were detected. Nearly 1000 interactions of each projectile have been analyzed. We present results on the multiplicity distributions, the pseudorapidity distributions, and the fragmentation of the projectile and target nuclei. It is shown that the mean number of intranuclear collisions in each interaction, calculated from a superposition model, provides a useful parameter for organizing the data. We conclude that there are no significant deviations even at these energies from models, such as the venus model, describing the interactions as being the superposition of individual nucleon-nucleon collisions.
