Multiplicity fluctuations in nuclear collisions at 158A GeV

نویسنده

چکیده

System size dependence of multiplicity fluctuations of charged particles produced in nuclear collisions at 158A GeV was studied in the NA49 CERN experiment. Results indicate a non-monotonic dependence of the scaled variance of the multiplicity distribution with a maximum for semi-peripheral Pb+Pb interactions with number of projectile participants of about 35. This effect is not observed in a string-hadronic model of nuclear collision HIJING.

Multiplicity Fluctuations in Heavy Ion Collisions at CERN SPS

The system size and centrality dependence of multiplicity fluctuations in nuclear collisions at 158A GeV as well as the energy dependence for the most central Pb + Pb collisions were studied by the NA49 experiment at CERN SPS. A strong increase of fluctuations was observed with decreasing centrality in C+C, Si+Si and Pb+Pb collisions. The string hadronic models (UrQMD, Venus, HIJING, HSD) can n...

Energy dependence of fluctuations in central Pb+Pb collisions from NA49 at the CERN SPS

The latest NA49 results on fluctuations of multiplicity and average transverse-momentum analyzed on an event-by-event basis are presented for central Pb+Pb interactions over the whole SPS energy range (20A 158A GeV). The scaled variance of the multiplicity distribution decreases with collision energy whereas the ΦpT measure of 〈pT 〉 fluctuations is small and independent of collision energy. Thu...

Energy and System-size Dependence of Two-particle Azimuthal Correlations of High-pT Charged Hadrons at the CERN SPS

Angular correlations of high-pT hadrons can serve as a probe of interactions of partons with the dense medium produced in high-energy heavy-ion collisions but other sources of such correlations exist which can be non-negligible SPS energies. In an attempt to determine the primary source, NA49 has performed an energy and system-size scan of two-particle azimuthal correlations in central Pb+Pb, S...

We propose to use multidimensional wavelet analysis for pattern recognition in high multiplicity events and consider some examples. Wavelet analysis reveals clustering phenomena in multiparticle production processes. Results of event-by-event studies of some nucleus– nucleus collisions at 158A GeV are reported. The clusterization topol-ogy is found to be different in different events. Typical p...
