Umut Gursoy (Utrecht University)29/09/2015, 14:00Correlations and FluctuationsContributed talkStrong magnetic fields produced in any non-central heavy ion collision are expected to affect the dynamics of the hot QCD matter produced in this collision. The magnetic field is time-dependent and the conducting medium is expanding, which leads to the induction of charged currents due to the combination of Faraday and Hall effects. We extend our previous work by studying the imprint of the...Go to contribution page

Yuji Hirono (Stony Brook University)29/09/2015, 14:20Correlations and FluctuationsContributed talkThe chiral magnetic effect (CME) has received considerable attention in recent years, particularly in the context of heavy-ion collisions. The anomaly-induced transport effects like the CME are macroscopic and are incorporated into hydrodynamic equations giving rise to "anomalous hydrodynamics". Theoretically, the CME is expected to occur in heavy-ion collisions. The data reported by STAR[1]...Go to contribution page

Liao Song (University of Houston)29/09/2015, 14:40Correlations and FluctuationsContributed talkDi-hadron correlations are a key observable in heavy-ion collisions, and play a critical role in establishing the equation of state for hot and dense matter. Long range di-hadron correlations, also known as the ridge, have been observed at the top RHIC energies and the LHC in A+A, p+A, and d+A collisions and are crucial to probing the collectivity of the various systems. We will present the...Go to contribution page

Peng Huo (State University of New York (US))29/09/2015, 15:00Correlations and FluctuationsContributed talkOne of the largest uncertainties in the modeling of heavy-ion collision arises from present poor understanding of the early-time dynamics especially in the longitudinal direction. Forward-backward (FB) multiplicity correlation has been regarded as a power observable on the early time dynamics since it probe directly the initial state density fluctuations in pseudorapidity. Previous studies of...Go to contribution page

Jiangyong Jia (State University of New York (US))29/09/2015, 15:20Correlations and FluctuationsContributed talkTwo-particle pseudorapidity correlations are measured using charged particles from sqrt(s_NN)=2.76 TeV Pb+Pb collisions by the ATLAS experiment at the LHC. The correlation function CN(η1, η2) is measured for different centrality intervals for | η1, η2|<2.4 and transverse momentum pT>0.5 GeV. An enhancement is observed along η- =η1-η2 ≈0 and a suppression is observed at large η- values. The...Go to contribution page

Evgeny Kryshen (CERN)29/09/2015, 15:40Correlations and FluctuationsContributed talkA double-ridge structure has been observed in two-particle correlations in p-Pb collisions at midrapidity and its origin is actively debated. Measurements at larger relative pseudorapidity can further improve our understanding of this phenomenon. The results on two-particle angular correlations between trigger particles in the forward pseudorapidity range (2.5 < |η| < 4.0) and associated...Go to contribution page

Panos Christakoglou (Nikhef National institute for subatomic physics (NL))29/09/2015, 16:00Correlations and FluctuationsContributed talkWe report comprehensive results on the balance function as a function of the pseudorapidity and azimuthal angle difference, ∆η and ∆φ respectively, between two charged particles. Results on the multiplicity and transverse momentum ($p_T$) dependence measured with ALICE in pp, p-Pb, and Pb-Pb collisions at 7 TeV, 5.02 TeV, 2.76 TeV are presented. The balance function in both ∆η and ∆φ becomes...Go to contribution page
