Erratum: Possible scenarios for soft and semihard component structure in central hadron-hadron collisions in the TeV region [Phys. Rev. D59, 094020 (1999)]

Abstract

Possible scenarios in hh collisions in the TeV region are discussed in full phase space. It is shown that at such high energies one should expect strong KNO scaling violation and a ln( √ s) increase of the average charged multiplicity of the semi-hard component, resulting in a huge mini-jet production.

Multiplicity dependence of inclusiveptspectra fromp−pcollisions ats=2

“…Apparently, the multiplicity increase in this analysis is dominated by increased frequency of events with a single hard scattering within a multiplicity class rather than bias toward more energetic partons. That scenario is consistent with the twocomponent model of [10].…”

“…The two-component model of nuclear collisions can be applied to (1) the event-frequency distribution on n ch (two or more negative-binomial distributions) [10,20], (2) the dependence of hp t i on n ch [8,16,26], (3) triggered jet correlations on ( , ) (correlations from soft and hard event classes) [21], and (4) the n ch dependence of the p t or y t spectrum shape [16]. The common theme is the relation of hard parton scattering to event multiplicity in the context of a ''soft'' underlying event.…”

“…The two-component model [10,20] states that the minimum-bias frequency distribution on event multiplicity from relativistic p-p collisions can be resolved into two components, each approximated by a negative-binomial distribution (NBD) with its own mean and k parameter. The two components correspond to events with (hard) and without (soft) significant hard parton scatters.…”

“…Alternatively, a model function can be formulated in terms of the two-component model of nuclear collisions [10], which identifies ''soft'' p-p collisions with no hard parton scatter and ''semihard'' collisions with at least one significant parton scatter (i.e., producing distinguishable hadron fragments). According to the two-component model the minimum-bias distribution on event multiplicity n ch can be decomposed into separate negative-binomial distributions (NBD) identified with soft and semihard event types.…”

Signals of new physics in global event properties inppcollisions in the TeV energy domain

“…Possible scenarios for pp collisions in the TeV energy domain, based on extrapolations from data and fits in the GeV region to charged particle multiplicity distributions, P n , and on the weighted superposition mechanism of two classes of events, i.e., soft (without minijets) and semihard (with minijets), each described by a negative binomial multiplicity distribution (NBMD) with characteristic parameters (n soft , k soft andn sh , k sh , respectively) have been discussed both in full phase space [1] and rapidity intervals [2].
