Two-dimensional discrete wavelet analysis of multiparticle event topology in heavy ion collisions
نویسندگان
چکیده
The event-by-event analysis of multiparticle production in high energy hadron and nuclei collisions can be performed using the discrete wavelet transformation. The ring-like and jet-like structures in two-dimensional angular histograms are well extracted by wavelet analysis. For the first time the method is applied to the jet-like events with background simulated by event generators, which are developed to describe nucleus-nucleus collisions at LHC energies. The jet positions are located quite well by the discrete wavelet transformation of angular particle distribution even in presence of strong background. PACS. 21.65.Qr – 25.75.Gz – 02.30.-f

Moments of event observable distribution in high energy heavy-ion collisions
Event-by-event fluctuations for high energy heavy-ion collisions are investigated. The normally used Φ-variables are calculated for pions. It was shown that multiparticle symmetrization (antisymmetrization) correlation has great influence on the value of Φ. Previous derivation of Φ actually neglected the multiparticle quantum correlation. So the explanation of Φ as a measure of the degree of eq...
متن کاملModeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
متن کاملEvent – by – event fluctuations in heavy – ion collisions and the quark – gluon string model
We apply dynamical string models of heavy–ions collisions at high energies to the analysis of event–by–event fluctuations. Main attention is devoted to a new variable proposed to study ”equilibration” in heavy–ions collisions. Recent results of the NA49 collaboration at CERN SPS are compared with predictions of the Quark–Gluon String Model (QGSM), which gives a good description of different asp...
