“…T ( n + 1 ) r ( K ) with two parameters ( n ) (average of the distribution) and K (width of the distribution), are being widely used to describe the multiplicity distributions (MD's) of produced charged particles in full phase space as well as in limited phase space, from a variety of collisions such as hadronic [I], hadron-nucleus [ 2 ] , nucleus-nucleus [3,4], e +e - [5], etc. The energy dependence of the ( n ) and K for hadronic collisions has also been studied by the UA5 Collaboration [I] in the energy range 10-900 GeV.…”

We have discussed the energy dependence of the parameters (n ) and K of the negative-binomial distributions for the full phase-space charged-particle multiplicity distributions in pp /pjT collisions. It was shown that, under the assumption that multiparticle production is a stationary branching process, there exists a relation between the two parameters (n ) and K . A similar relation can also be derived empirically, from information-theoretic entropy considerations. The energy dependence of one parameter then automatically determines the energy dependence of the other. It was then argued from entropy considerations that there should be an upper bound for ( n ) or conversely a lower bound for K as a function of energy. New parametrizations for the energy dependence of K were given, taking into account that K should have a lower bound, which together with the relation between the parameters ( n ) and K predicts that the average number of particles cannot be increased indefinitely with increasing c.m. system energy.

“…During the past years a great deal of attention has been given to the experimental and the theoretical studies of hadronnucleus (h-A) and nucleus-nucleus (A-A) collisions at high energies [1][2][3][4][5][6][7][8]. The aim of this work is to study the space-time development [9] of hadronic interaction under extreme conditions of high energy and baryon densities within nuclear dimensions, which are otherwise available only in the hot early Universe.…”

The total reaction cross sections for the interaction of 16 O with emulsion nuclei ( 16 O-Em) at energies: 0.2, 2.1, 3.6, 14.6, 60.0, and 200.0A GeV have been calculated in the framework of the Coulomb-modified Glauber model. A similar calculation in case of proton-emulsion (p-Em) interactions is carried out at the same energies. For both types of interactions, the corresponding projectile and target participants beside the corresponding binary collisions have been calculated for the same energies. Then the averages of these quantities have been obtained. These averages have been used in the calculations of the corresponding average multiplicity of the shower particles (s-particles) in the case of the 16 O-Em interaction. The agreement between the calculated total reaction cross sections and the corresponding experimental data is quite good. Also, a good agreement between the calculated average multiplicities of the shower particles and the corresponding experimental data has been obtained. Résumé: Utilisant le modèle de Glauber avec modification coulombienne, nous avons calculé les sections efficaces totales pour l'interaction 16 O avec les noyaux d'une émulsion ( 16 O-Em) aux énergies 0,2A, 2,1A, 3,6A, 14,6A et 200A GeV. Nous faisons simultanément un calcul similaire pour le cas proton-émulsion aux mêmes énergies. Dans les deux cas, nous avons calculé aux mêmes énergies les participants des projectile et cible en plus des collisions binaires correspondantes. Nous avons évalué les moyennes de ces quantités, qui ont été utilisées dans le calcul des multiplicités moyennes correspondantes du jet sortant de particules (shower) dans le cas 16 O-Em.

The analysis of neutron n and singly charged particle Q=1 participated from 16 O at 4.5A GeV/c interactions with emulsion nuclei are presented. The average multiplicities of shower particle for n and Q=1 stay more or less constant when compared with analogous data on P-A at similar momentum. The multiplicity distributions as well as the average values of the various secondary particles are studied, discussed and compared with the calculations according cascade evaporation model. The results lead to assume that the n and Q=1 from 16 O tend to collide peripherally with target emulsion or in other words to make gentle reactions.
