“…Recently, the study of the spike-centers has been carried out for hadronic interactions at 205-306 GeV/c [21]. The double-peak shape of the η 0 -distribution for pp-collisions vs. a single-peak structure in π/Kp-interactions have been observed in agreement with the coherent gluon-jet emission model [10].…”

Study of multiparticle spikes in central 4.5A GeV/c C-Cu collisions

An analysis of local fluctuations, or spikes, is performed for charged particles produced in central C-Cu collisions at 4.5 GeV/c/nucleon. The distributions of spike-centers and the maximum density distributions are investigated for different narrow pseudorapidity windows to search for multiparticle dynamical correlations. Two peaks over statistical background are observed in the spike-center distributions with the structure similar to that expected from the coherent gluon radiation model and recently found in hadronic interactions. The dynamical contribution to maximum density fluctuations are obtained to be hidden by statistical correlations, though behavior of the distributions shows qualitative agreement with that from the one-dimensional intermittency model. The observed features of the two different approaches, coherent vs. stochastic, to the formation of the local dynamical fluctuations are discussed.

“…The two-or three-dimensional pattern could be, however, much reacher in structure compared to its one-dimensional projection. In particular, Lego-plots have been used for jets, and some ring-like densely populated regions (corresponding to semi-isolated dense groups on the pseudorapidity axis) have been observed in experiment [2,3].…”

Pattern Recognition in High Multiplicity Events

In very high energy collisions, many particles are produced and distributed in the available phase space volume in various ways. With advent of new accelerator facilities (especially, for nucleus-nucleus collisions), the problem of pattern recognition in high multiplicity events becomes very actual in order to classify such events and to separate those of them with some special features (e.g. ring-like events, jets and other regular patterns). This paper presents the first attempt to use wavelet technique for pattern recognition in nucleus-nucleus collisions. After describing the method in general, we demonstrate its power by applying it to a single event of Pb-Pb collision at 158A GeV with 1072 charged particles produced and discuss results obtained for some other events. Further extension of the method is proposed.Comment: 6 pages, LATEX, 4 Figs (PostScript); to be published in Mod.Phys.Lett.

“…The ring-like and spotty two-dimensional plot leading to such maxima was confirmed by the wavelet analysis of the cosmic ray event [18]. Let us note that some indications on similar effects in hadronic reactions at lower energies were obtained with a special selection of events in the high statistics sample [19] as well as by the wavelet analysis of individual events [20].…”

The Two Types of Cherenkov Gluons at LHC Energies

Beside comparatively low energy Cherenkov gluons observed at RHIC, there could be high energy gluons at LHC, related to the high energy region of positive real part of the forward scattering amplitude. In both cases they give rise to particles emitted along some cone. The characteristics of the cones produced by these two types of gluons are different. Therefore different experiments are needed to detect them. The cosmic ray event which initiated this idea is described in detail.
