On Event–by–Event Fluctuations in Nuclear Collisions
We demonstrate that a new type of analysis in heavy–ion collisions, based on an event– by–event analysis of the transverse momentum distribution, allows us to obtain information on secondary interactions and collective behaviour that is not available from the inclusive spectra. Using a random walk model as a simple phenomenological description of initial state scattering in collisions with heav...
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 of Transverse Momentum in Elementary Collisions at 250 Gev/c
We present a study of event-by-event fluctuations of transverse momentum in πp and Kp collisions at 250 GeV/c and the corresponding PYTHIA Monte Carlo results for πp collisions. The dependence of Φpt on event and particle variables are investigated in detail. We find that Φpt are all negative for different average transverse momentum per event sample. The 〈pt〉N ∼ N correlation may not be the on...
متن کامل2 00 2 Event - by - event fluctuations in heavy ion collisions
We discuss the physics underlying event-by-event fluctuations in rel-ativistic heavy ion collisions. We will argue that the fluctuations of the ratio of positively over negatively charged particles may serve as a unique signature for the Quark Gluon Plasma.
متن کاملEvent-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 ...
