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 کاملEvent by Event fluctuations and Inclusive Distributions
Event-by-event observables are compared with conventional inclusive measurements. We find that moments of event-by-event fluctuations are closely related to inclusive correlation functions. Implications for upcomming heavy ion experiments are discussed. 1. It is now widely recognized that studies of event-by-event fluctuations observed in high energy multi-particle reactions may become an impor...
متن کاملEvent-by-event analysis of heavy ion collisions and thermodynamical fluctuations
The event-by-event analysis of heavy ions collisions is becoming possible with advent of large acceptance detectors: it can provide dynamical information which cannot be obtained from inclusive spectra. We identify some observables which can be related to standard thermodynamical theory of fluctuations and therefore may provide information about properties of hadronic matter at the freeze-out s...
