Recent results on event-by-event fluctuations from the RHIC Beam Energy Scan program in the STAR experiment
Event-by-event fluctuations of global observables in relativistic heavy-ion collisions are studied as probes for the QCD phase transition and as tools to search for critical phenomena near the phase
Event-by-Event Multiplicity Fluctuations in Heavy-Ion Collisions.
Multiplicity distributions of produced particles and their event-by-event fluctuations are studied using the AMPT model in the default and string melting modes. In addition to being sensitive to the
Fluctuations in Charged Particle Multiplicities in Relativistic Heavy-Ion Collisions
Multiplicity distributions of charged particles and their event-by-event fluctuations have been compiled for relativistic heavy-ion collisions from the available experimental data at Brookhaven

Heavy-ion collisions at relativistic energies probe matter at extreme conditions of temperatures and energy densities. The study of event-by-event fluctuations of experimental observables is crucial
Probing the bulk medium in relativistic heavy ion collisions using two-particle correlations
Measurements of charge-independent and charge-dependent two-particle correlations for Au-Au collisions at √sNN = 130 GeV from the STAR experiment are presented as functions of transverse momentum pt
Event-by-event fluctuations in relativistic nuclear collisions within microscopic transport approach — HSD
In this poster a review of fluctuations within a transport model approach has been presented. The scaled variances of multiplicity fluctuations in nucleus-nucleus collisions at SPS and RHIC energies
Experimental Results on Charge Fluctuations in Heavy-Ion Collisions
We present a subset of experimental results on charge fluctuation from the heavy-ion collisions to search for phase transition and location of critical point in the QCD phase diagram. Measurements


Event-by-event fluctuations of the charged particle ratio from nonequilibrium transport theory
The event-by-event fluctuations of the ratio of positively to negatively charged hadrons are predicted within the UrQMD model. Corrections for finite acceptance and finite net charge are derived.
Correlations and fluctuations in high-energy nuclear collisions.
The interplay between cross-section fluctuations, from color transparency and opacity, and nuclear correlations is calculated and found to be able to account for large fluctuations in transverse energy spectra.
Collective expansion in high-energy heavy ion collisions
Transverse mass spectra of pions, kaons, and protons from the symmetric heavy-ion collisions 200AGeV S+S and 158AGeV Pb+Pb, measured in the NA44 focusing spectrometer at CERN, are presented. The mass
Fluctuations of particle ratios and the abundance of hadronic resonances
In this letter we will argue that the event-by-event fluctuations of the ratio of positively over negatively charged pions provides a measurements of the number of rho and omega mesons right after
