On Transverse Momentum Event–by–Event Fluctuations in String Hadronic Models
نویسنده
چکیده
Transverse momentum event–by–event fluctuations are studied within the string– hadronic model of high energy nuclear collisions, LUCIAE. Data on non–statistical pT fluctuations in p+p interactions are reproduced. Fluctuations of similar magnitude are predicted for nucleus–nucleus collisions, in contradiction to the preliminary NA49 results. The introduction of a string clustering mechanism (Firecracker Model) leads to a further, significant increase of pT fluctuations for nucleus–nucleus collisions. Secondary hadronic interactions, as implemented in LUCIAE, cause only a small reduction of pT fluctuations.

Influence of Impact Parameter Fluctuations on Transverse Momentum Fluctuations
The preliminary NA49 results on the energy dependence of transverse momentum fluctuations over the whole Super Proton Synchrotron (SPS) energy range exhibit an unexpected effect. The ΦpT fluctuation measure used by the NA49 experiment manifests a different behavior for different charge combinations. Whereas the ΦpT is consistent with zero and independent of energy for negatively charged particl...

We perform an event-by-event analysis of the transverse momentum distribution of final state particles in central Pb(160AGeV)+Pb collisions within a microscopic non-equilibrium transport model (UrQMD). Strong influence of rescattering is found. The extracted momentum distributions show less fluctuations in A+A collisions than in p+p reactions. This is in contrast to simplified p+p extrapolation...
متن کاملCorrelations at RHIC and the Clustering of Color Sources
We present our results on transverse momentum fluctuations and multiplicity fluctuations in the framework of the clustering of color sources. In this approach, elementary color sources stringsoverlap forming clusters, so the number of effective sources is modified. These clusters decay into particles with mean transverse momentum that depends on the number of elementary sources that conform eac...
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...

The PHENIX Experiment at the Relativistic Heavy Ion Collider has made measurements of event-by-event fluctuations in the net charge, the mean transverse momentum, and the charged particle multiplicity as a function of collision energy, centrality, and transverse momentum in heavy ion collisions. The results of these measurements will be reviewed and discussed.. 1. Introduction The PHENIX experi...
