“…(15) and (17) we conclude that the central plateau cannot rise faster than y max 2 or ln 2 s and the total multiplicity cannot rise faster than y max 3 or ln 3 s. The only possible way to get faster dependence is to have ͱ s dependent K, or faster rising g U (for instance an exponential). Judging from Fig.…”

Universal transition curve in pseudorapidity distribution

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.
