Multiple production in the Monte Carlo string fusion model

Density saturation and the decrease of the normalised width of the multiplicity distribution in high energy pp collisions

“…We shall work in the framework of the dual string model [10]. Saturation, in this case, results from clustering and percolation of strings.…”

“…In particular, the relative importance of strange baryon production from hadronic rescattering differs between calculations [18,19], depending on both the evolution of the system and the scattering cross sections assumed. Exotic dynamical mechanisms that have been proposed for strange baryon production include, for example, Color String Ropes [20], String Fusion [21] and Multi-mesonic Reactions [22]. All require a high local energy density and therefore suggest that strangeness production occurs early in the collision.…”

Collective behavior in nuclear interactions and shower development

“…In this paper we have tried to study the consequences on shower development of the existence of collective mechanisms in nucleus-nucleus collisions which modify secondary particle production. These mechanisms have been proposed [9,11,19,20] to explain several experimental facts in heavy ion collisions. We have tried two extreme scenarios which, in our view, contain the most plausible extreme possibilities: first, string fusion [9] which strongly affects multiplicities but has very little effect on the forward region; second, a different picture of strong fields [11] which strongly increases the stopping.…”
