“…Many models for hadron-hadron col-lisions developed in the 1970's [36][37][38][39][40] also had this type of dn / d. As will be shortly shown, this Woods-Saxon form is not compatible with the transition region universality and hence it is unlikely that this is the right form of dn / d. Nevertheless we feel that it is worth considering the Woods-Saxon form here because it gives an example of slowly changing (as opposed to universal) limiting fragmentation curve.…”

We show that an unambiguous way of determining the universal limiting fragmentation region is to consider the derivative ͑d 2 n / d 2 ͒ of the pseudorapidity distribution per participant pair. In addition, we find that the transition region between the fragmentation and the central plateau regions exhibits a second kind of universal behavior that is only apparent in d 2 n / d 2 . The ͱ s dependence of the height of the central plateau ͑dn / d͒ =0 and the total charged particle multiplicity n total critically depend on the behavior of this universal transition curve. Analyzing available Relativistic Heavy-Ion Collider (RHIC) data, we show that ͑dn / d͒ =0 can be bounded by ln 2 s and n total can be bounded by ln 3 s. We also show that the deuteron-gold data from RHIC has exactly the same features as the gold-gold data indicating that these universal behaviors are a feature of the initial state parton-nucleus interactions and not a consequence of final state interactions. Predictions for LHC energy are also given.

Phys. Rev. P73, 975 (1968).The idea that qualitative and quantitative differences between different classes of models for elementary-particle production in single-particle inclusive reactions will emerge from studies of reactions on nuclei has been put forward many times. 1 " 3 In this note we contrast the results of realistic calculation of production processes on nuclei to show what experiments can differentiate between models of the elementary production process, and to comment on the (sparse) data now available in this area.In general, current models for multiparticle production can be divided into "coherent-production models" (CPM) (here we might include 4 fragmentation, nova, and diffraction-dissociation models), in which the final state arises from the decay of a long-lived intermediate excitation, and the

The production mechanism of a particle in multi-particle production is distinguished according to whether it is composed of urbaryons coming partly from incident particles, or is composed only of ones newly created in the collision. The former mechanism, which is different for a particle and its antiparticle, gives constant multiplicity and rapid limiting behaviour in the fragmentation region. In the case of pp collisions, the limiting energy for this mechanism is somewhat above 10 Ge VI c. The latter mechanism gives the same increasing multiplicity and distribution for a particle and its antiparticle. The scaling energy in the latter mechanism including x-0 is quite different for rr, K and p, indicating strong mass dependence. The scaling energies in the reactions pp-7rr-X, K-X and pX are around 30 GeVIc, a few hundred GeVIc and 1 TeVIc, respectively. It is conjectured that the average multiplicity differences such as nn•-nn-, riK•-nKbecome energy independent at energies somewhat above 10 Ge VIc for pp and K+p collisions. a) Typical diagrams for baryon+baryon-7baryon<•>+X. b) Typical diagrams for antibaryon+baryon-7baryon<•>+X, not appearing in a).
