Charged Particle Multiplicities and Interaction Cross-sections in High-energy Nuclear Collisions

The NA35 collaboration Bamberger, A. ; Bangert, D. ; Bartke, J. ; et al.
Phys.Lett.B 205 (1988) 583-589, 1988.
Inspire Record 262284 DOI 10.17182/hepdata.42035

Inelastic cross sections at 60 and 200 GeV/nucleon are determined in a streamer chamber for 16 O on several nuclear targets. Charged particle multiplicity distributions for inelastic and central collisions are studied and compared with theoretical predictions. The inelastic cross section exhibit a geometrical dependence on nuclear radii. The multiplicity data are governed by the collision geometry. They are consistent with a picture of superposition of independent nucleon-nucleus interactions.

Study on fractality in nucleus-nucleus interaction at a few GeV/c

Ghosh, D. ; Ghosh, P. ; Deb, A. ; et al.
Phys.Lett.B 272 (1991) 5-10, 1991.
Inspire Record 325536 DOI 10.17182/hepdata.29281

The scaled factorial moments, F q and fractal moments, G q have been measured and their power law variation as a function of size of the pseudorapidity interval has been studied in the central region of the pseudorapidity distribution of the produced charged particles in quasi-central and central collisions of 16 O + Ag Br at 2.1 GeV c per nucleon and 24 Mg + Ag Br at 4.5 GeV c per nucleon. The smooth spectral function f ( α q ), characterizing the fluctuation in the pseudorapidity distribution and the generalised dimensions D q have been derived from G q moments. The analyses reveal a self-similarity in multiparticle production in nucleus-nucleus interactions at an incident momentum of a few GeV/ c per nucleon. Interesting observations can be very effective in establishing multifractality in multiparticle production at this energy range.

Charged Particle Multiplicity Distributions in Oxygen - Nucleus Collisions at 60-{GeV} and 200-{GeV} Per Nucleon

The HELIOS collaboration Akesson, T. ; Almehed, S. ; Angelis, A.L.S. ; et al.
Nucl.Phys.B 333 (1990) 48-65, 1990.
Inspire Record 281287 DOI 10.17182/hepdata.33112

Multiplicity distributions of charged particles produced in the pseudorapidity range 0.9 < η lab < 5.5 were measured in oxygen-nucleus collisions for Al, Ag, and W target nuclei at incident energies of 60 and 200 GeV per nucleon. The multiplicity differential cross sections and the pseudorapidity distributions as a function of transverse energy are presented for the various target nuclei. The correlation between charged multiplicity and transverse energy is studied as a function of transverse energy. Data are compared with predictions of the IRIS and FRITIOF generators.
