Experimental data on multiplicities and correlations of charged particles of different types produced in collisions of 4.5 A GeV/c carbon-12 with emulsion are reported and discussed. The data are compared with the results of other experiments on nucleus–nucleus and hadron–nucleus collisions. It is found that the particle production mechanism in nucleus–nucleus collisions is almost the same as in hadron–nucleus collisions. It is also observed that the shower particles' multiplicity distributions obey a KNO type scaling law, which supports the aforementioned result.

The results of the multiplicity distributions of shower, grey, black, and heavily ionizing charged particles from induced16 reactions at 200A GeV are presented. The results are compared with the predictions of the Lund Monte Carlo code fritiof, the multichain model by Ranft, and the Monte Carlo code venus.

PROPERTIES OF PROJECTILE FRAGMENTS FROM C-12 EMULSION INTERACTIONS AT 4.5.A/GEV/C

Ahmad, M.S. ; Khan, M.Q.R. ; Hasan, R. ;

2550 interactions of 12 C in emulsion at 4.5 A GeV / c have been used to study the properties of projectile fragments. The multiplicity and projected angular distributions of projectile fragments in different target groups have been studied. The production cross section of the reaction in which projectile 12 C breaks up into two Z = 3 fragments is found to be 6.6 × 10 −3 of the total inelastic cross section. The projected angular distributions of fragments exhibit features of limiting fragmentation. Statistically significant azimuthal correlations among fragments in the azimuthal plane indicates that the fragmenting nucleus gets a transverse momentum during the collision.

Multiplicity of Charged Particles in 800-{GeV} $p p$ Interactions

The LEBC-MPS collaboration Ammar, R. ; Aziz, T. ; Banerjee, S. ; et al.

Phys.Lett.B 178 (1986) 124-128, 1986.

Inspire Record 231133 DOI 10.17182/hepdata.6558

Results are reported concerning the charged-particle multiplicity distribution obtained in an exposure of the high-resolution hydrogen bubble chamber LEBC to a beam of 800 GeV protons at the Fermilab MPS. This is the first time that such data have been available at this energy. The distribution of the number n ch of charged particles produced in inelastic interactions obeys KNO-scaling. The average multiplicity is 〈 n ch 〉 = 10.26±0.15. For n ch ⩾8 the data can be well fitted to a negative binomial. The difference between the overall experimental multiplicity distribution and that resulting from the latter fit is in agreement with the contribution expected from diffractive processes.
