Charged particle multiplicities in nuclear collisions at 200-GeV/N

The NA35 collaboration Bächler, J. ; Bartke, J. ; Bialkowska, H. ; et al.
Z.Phys.C 51 (1991) 157-162, 1991.
Inspire Record 320907 DOI 10.17182/hepdata.14983

Data on multiplicities of charged particles produced in proton-nucleus and nucleus-nucleus collisions at 200 GeV per nucleon are presented. It is shown that the mean multiplicity of negative particles is proportional to the mean number of nucleons participating in the collision both for nucleus-nucleus and proton-nucleus collisions. The apparent consistency of pion multiplicity data with the assumption of an incoherent superposition of nucleon-nucleon collisions is critically discussed.

Multistep production of eta and hard pi0 mesons in subthreshold Au Au collisions.

Wolf, A.R. ; Appenheimer, M. ; Averbeck, R. ; et al.
Phys.Rev.Lett. 80 (1998) 5281-5284, 1998.
Inspire Record 471975 DOI 10.17182/hepdata.41989

The neutral π0 and η mesons are studied in 197Au−197Au collisions at an incident energy of 800AMeV, substantially below the threshold for η production in N−N collisions. While the gross π0 multiplicity increases almost linearly with the number of participant nucleons, the multiplicities of η and hard π0 mesons show a stronger than linear dependence. The nonlinearity is governed by the average transverse-mass excess 〈mt〉−(s−2mN) of the mesons and is insensitive to their final-state interaction in the nuclear medium.

Central Collisions of 14.6-{GeV}/nucleon, 60-{GeV}/nucleon, and 200-{GeV}/nucleon $^{16}$O Nuclei in Nuclear Emulsion

Barbier, L.M. ; Freier, P.S. ; Holynski, R. ; et al.
Phys.Rev.Lett. 60 (1988) 405-407, 1988.
Inspire Record 264260 DOI 10.17182/hepdata.2969

Central collisions of O16 nuclei with the Ag107 and Br80 nuclei in nuclear emulsion at 14.6, 60, and 200 GeV/nucleon are compared with proton-emulsion data at equivalent energies. The multiplicities of produced charged secondaries are consistent with the predictions of superposition models. At 200 GeV/nucleon the central particle pseudorapidity density is 58±2 for those events with multiplicities exceeding 200 particles.

Intermediate mass fragment emission in heavy ion collisions: Energy and system mass dependence

Sisan, D. ; Bauer, W. ; Bjarki, O. ; et al.
Phys.Rev.C 63 (2001) 027602, 2001.
Inspire Record 552389 DOI 10.17182/hepdata.25393

Emission of intermediate mass fragments (IMFs) (Z>~3) from central collisions of 40Ar+45Sc (E/A=35–115 MeV), 58Ni+58Ni (E/A=35–105 MeV), and 86Kr+93Nb (E/A=35–95 MeV) was studied. For each system, the average number of IMFs per event increased with beam energy, reached a maximum, and then decreased. The beam energy of peak IMF production increased linearly with the combined mass of the system. The number of IMFs emitted at the peak also increased with the system mass. Percolation calculations showed a weaker dependence of the peak beam energy and the number of IMFs on the total mass of the system.
