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 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 ...
متن کاملEvent by event Net Charge Fluctuations
We present analyses of event-by-event dynamical net charge fluctuations measured in130 and 200 GeV Au Au collisions with the STAR detector. The dynamical net charge fluctuations are evaluated using the ν+−,dyn observable. Dynamical fluctuations measured in Au Au collisions at 130 and 200 GeV are finite, and exceed charge conservation limits. They deviate from a perfect 1/N scaling and provide a...
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 کاملOverview of Event-by-event Fluctuations *
With the advent of large acceptance detectors it became possible to observe not one but tens or even hundreds of particles produced in a single collision of relativistic nuclei. Such a multi-particle state constitutes an event corresponding to a single high-energy collision. Event-by-event analysis is potentially a powerful technique to study relativistic heavy-ion collisions, as magnitude of f...
