128. Determination of classes of events in multiplicity and its relevance to centrality in high energy Pb-Pb and p-Pb collisions in different MC models

Tatiana Drozhzhova (Saint-PetersburgState University)

Section D: Deconfinement

We present the critical review of estimates of centrality in AA and pA collisions that are usually done by selection of classes of events with certain charged particles multiplicity. Results of MC simulations in different models are presented. They include the Standard Glauber, the Modified Glauber model [1] and HIJING[2] event generator (with gluon shadowing) MC calculations. We...

57. Modeling the influence of string collective phenomena on the long range rapidity correlations between the transverse momentum and the multiplicities

Section D: Deconfinement

The long-range rapidity correlations between the multiplicities (n-n) and the transverse momentum and the multiplicity (pT-n) of charge particles are analyzed in the framework of the simple string inspired model with two types of sources. The sources of the first type correspond to the initial strings formed in a hadronic collision. The sources of the second type imitate the appearance of the...

54. Hadronic resonance production measured by the ALICE experiment at LHC

Section D: Deconfinement

Hadronic resonances are among the most interesting probes of the hot and dense matter created in Pb--Pb collisions. Due to their short lifetime, they are sensitive to the anticipated chiral symmetry restoration as well as to suppression and regeneration due to hadronic interactions in the final state. At intermediate and high transverse momenta ($p_{\mathrm T}$) resonances which cover the...

82. Transverse momentum dependence of spectra of cumulative particles produced from droplets of dense nuclear matter

Vladimir Vechernin (St. Petersburg State University (RU))

9/12/14, 3:00 PM

Section D: Deconfinement

The approach relies on a microscopic treatment of cumulative phenomena based on perturbative QCD calculations of the corresponding quark diagrams near the thresholds [1]. This enables to find the asymptotic behavior of the structure functions of nuclear fluctons – the dense drops of nuclear matter in nuclei composed of a few nucleons. As a result, in the framework of the approach the nuclear...

164. Constraints on the percolation model from anomalous centrality evolution of two-particle correlations in Au-Au collisions at √sNN = 62 and 200 GeV

Dr Grigory Feofilov (Saint-Petersburg State University)

9/12/14, 3:30 PM

Section D: Deconfinement

Some sudden change in two-dimensional two-particle angular correlations (i.e. the onset of a so-called near-side «ridge» structure, localized in azimuth and extended in pseudorapidity) was observed by STAR collaboration at RHIC in AuAu collisions at 62 and 200 GeV [1]. It was shown for the first time that this change occurs at a specific Au-Au centrality, common to both energies. These...
