Net Charge Fluctuations inAu+AuInteractions atsNN

Abstract: Data from Au + Au interactions at sqrt[s(NN)]=130 GeV, obtained with the PHENIX detector at the Relativistic Heavy-Ion Collider, are used to investigate local net charge fluctuations among particles produced near midrapidity. According to recent suggestions, such fluctuations may carry information from the quark-gluon plasma. This analysis shows that the fluctuations are dominated by a stochastic distribution of particles, but are also sensitive to other effects, like global charge conservation and resonance d… Show more

“…Event-by-event particle fluctuations have elicited theoretical [31,32,33,34] and experimental interest [35,36,37,38], both as a consistency check for existing models, as a test of hadron gas equilibration and as a way to search for new physics. The ability of the SHM to describe not just averages, but event-by-event multiplicity fluctuations has however not been widely investigated, and its applicability is currently a matter of controversy.…”

“…Higher-order Fourier harmonics are measured with respect to the corresponding harmonic plane angles Φ n [6]. The collective behavior of the QGP has been studied using the azimuthal anisotropy of emitted particles detected in experiments at the Relativistic Heavy Ion Collider (RHIC) [7][8][9] and the Large Hadron Collider (LHC) [10][11][12][13][14][15][16][17][18][19][20][21].…”

“…It is widely accepted that measurement of charge fluctuations is a useful tool to identify whether or not a deconfined QCD state is created in AB collisions. All major collaborations on high-energy heavy-ion experiments have pursued such measurements on an event-by-event basis [8][9][10][11][12][13]. The observables for fluc- * Electronic address: amitabha 62@rediffmail.com tuation measurements used by different groups may not always be the same, but the underlying correlation functions in all cases remain more or less identical.…”
