“…Study of the characteristics of grey particles produced in high energy hadron-nucleus (h-A) interactions has attracted a great deal of attention in the last decade (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), because of the fact that the number of grey particles having velocity in the interval 0.3 S P S 0.7. (N ) is considered a good measure of the number of collisions (vj made by the incident hadron inside the struck nucleus (1 1 -15).…”

The emission characteristics of secondary charged particles produced in 400 GeV proton-emulsion interactions were compared with those obtained at other energies. The results revealed that the angular distribution of grey particles does not depend on the nature and energy of the projectile. The dependence of the average multiplicity of the grey, black, shower, and heavily ionizing tracks on the mass of the target nucleus (A) and the nature and energy of the projectiles are also examined. The ratio of the valance quarks in pions ( n -) and protons (p) was found to be almost equal to the ratio of the grey particles produced in .rr--A and p-A collisions at the same energy. The values of the normalized moments of the multiplicity distributions of charged shower particles in different N,, intervals were found to be nearly the same. However, this value increased with increasing values of the moment index, K. Finally, the values of the normalized and central moments were almost equal for both p-p and p-A interactions.Les caractCristiques de I'emission de particules secondaires chargtes dans les interactions de protons de 400 GeV dans des Cmulsions sont comparCes avec celles qu'on a observCes i d'autres Cnergies. Les rCsultats rCvklent que la distribution angulaire des particules grises ne dipend pas de la nature et de 1'Cnergie du projectile. On examine aussi l'influence de la masse du noyau cible (A), ainsi que de la nature et de 1'Cnergie des projectiles, sur la multiplicitC moyenne des particules grises ou noires, des cascades et des traces de forte ionisation. On observe que le rapport des quarks de valence dans les pions (a-) et les protons (p) est presque Cgal au rapport des particules grises produites dans les collisions n--A et p-A B la m&me Cnergie. On trouve que les valeurs des moments normalisCs des distributions de multiplicitt dans les cascades de particules chargCes sont presque les mCmes dans differents intervalles N,. La valeur augmente cependant avec la valeur de l'indice K du moment. Enfin, les valeurs des moments normalisCs et des moments centraux sont presque les mCmes pour les interactions p-p et les interactions p-A.[Traduit par la revue]Can. I. Phys. 68, 67 (1990)

“…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.

“…The slope of this linear relationship is independent of the incident energy and projectile mass number as reported from cosmic-ray analysis [29,30] and nucleus-nucleus interactions [2,31]. Its value is nearly twice that of hadron-induced interactions [26,32]. The dispersions of the multiplicity distributions are smaller than < n s > due to the limited range of impact parameters for the central collisions.…”

The multiplicity and pseudorapidity distributions of shower particles produced in interactions of the 24 Mg at 4.5A GeV/c was studied in nuclear emulsion. The results indicated that the multiplicity distributions of shower particles produced in the collisions depend on the projectile mass. The pseudorapidity distributions are approximately Gaussian in shape. Also, the peaks of the pseudorapidity distributions of shower particles tend to shift towards the lower values of the pseudorapidity with increasing number of the shower particles.PACS Nos.: 25.75.-q, 29.40.Rg Résumé : Nous étudions dans des émulsions nucléaires les distributions de multiplicité et de pseudo-rapidité des gerbes de particules produites dans des interactions sur du 24 Mg à 4,5A GeV/c. Les résultats indiquent que les distributions de multiplicité de particules dans les gerbes dépendent de la masse du projectile. Les distributions de pseudo-rapidité sont approximativement gaussiennes. De plus, les pics dans la distribution de pseudo-rapidité se déplacent vers les valeurs inférieures de pseudo-rapidité avec l'augmentation du nombre de particules dans la gerbe.[Traduit par la Rédaction]
