Non-monotonic behavior of multiplicity fluctuations
We discuss recently measured event-by-event multiplicity fluctuations in relativistic heavy-ion collisions. It is shown that the non-monotonic behavior of the multiplicity fluctuations as a function of collision centrality can be fully explained by the correlations between produced particles.. 1. Introduction Event-by-event fluctuations in heavy-ion collisions have been recently measured both a...
متن کاملMultiplicity Fluctuations in Dis
The studies of multiplicity fluctuations in restricted domains of the phase space reveal the nature of particle correlations and are sensitive to the dynamics of the underlying process. The hadronic final state in DIS is a result of a hard partonic scattering at a large momentum transfersQ ≫ Λ. A subsequent parton cascade development down to some QCD cut-off Q0 and fragmentation occuring at sma...
متن کاملQcd Showering and Multiplicity Fluctuations
Multiplicity uctuations are investigated for hadron-hadron collisions (NA22) as a function of the cms opening angle between secondary particles. The angular dependence is very diierent for unlike-charge and like-charge particle combinations. For the latter, factorial moments increase with decreasing opening angle approximately as a power law. The dependence is stronger for central production-an...
متن کاملMedium-modified average multiplicity and multiplicity fluctuations in jets
The energy evolution of average multiplicities and multiplicity fluctuations in jets produced in heavy-ion collisions is investigated from a toy QCD-inspired model. In this model, we use modified splitting functions accounting for medium-enhanced radiation of gluons by a fast parton which propagates through the quark gluon plasma. The leading contribution of the standard production of soft hadr...
متن کاملLarge-deviation analysis of multiplicity fluctuations
In this paper we introduce and briefly discuss some of the basic results of large-deviation theory. We propose that large-deviation analysis be used as a tool complementary to the usual intermittency analysis because, as we show, systems exhibiting similar factorial moment behaviour may be quite different from the point of view of large-deviation properties. Large-deviation functions for some s...
