Event-by-Event Fluctuations in Heavy Ion Collisions and the QCD Critical Point
The event-by-event fluctuations of suitably chosen observables in heavy ion collisions can teach us much about the thermodynamic properties of the hadronic system at the time interactions freeze out. By studying these fluctuations as a function of varying control parameters like collision energy, centrality, ion size and rapidity, it is possible to learn much about the phase diagram of QCD. As ...
متن کاملQCD critical point and event-by-event fluctuations in heavy ion collisions
The goal of this work is to motivate a program of heavy ion collision experiments aimed at discovering an important qualitative feature of the QCD phase diagram — the critical point at which a line of first order phase transitions separating quark-gluon plasma from hadronic matter ends [1] (see Fig. 1). The possible existence of such an endpoint E has recently been emphasized and its universal ...
متن کاملStudy of Event-by-event Fluctuations in Heavy Ion Collisions
We propose Kolmogorov-Smirnov test as a means for recognising event-by-event fluctuations of rapidity distributions in relativistic heavy ion collisions. Such fluctuations may be induced by the spinodal decomposition of the rapidly expanding system during the 1st order quark-hadron phase transition.
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...
متن کاملEvent-by-Event Fluctuations of Transverse Momentum and Multiparticle Clusters in Relativistic Heavy-Ion Collisions
This paper is based on our recent analysis [1] of the eventby-event fluctuations of the mean transverse-momentum measured by PHENIX [2] and STAR [3, 4] Collaborations at RHIC. The discussed new data has extended our knowledge of the phenomena studied intensely in recent years [5–20]. One of the central issues in this field is whether the pT fluctuations at intermediate momenta result from jets ...
