Correlations and fluctuations
Parallel
Angular correlations between unidentified hadron trigger and
associated particles are measured by the ALICE experiment for $0.5 <
p_{t}^{(t),(a)} < 15$ GeV/c, where $p_t^{(t)} > p_t^{(a)}$. The
modification of conditional yields in central Pb--Pb collisions is
measured with respect to p--p ($I_{AA}$) and with respect to peripheral
events ($I_{CP}$). Significant suppression is observed on...

Measurements of charged dihadron correlations from the CMS collaboration are presented for PbPb collisions at a center-of-mass energy of 2.76 TeV per nucleon pair over a broad range of pseudorapidity and the full range of azimuthal angle. With its large pseudorapidity coverage (|$\eta$|<2.4), the CMS tracker is ideally suited for detailed analyses of both short and long-range charged hadron...

We present measurements of untriggered di-hadron correlations as a function of centrality in Pb-Pb \sqrt{s_{NN}} =2.76 TeV collisions, for charged hadrons with p_{T} > 0.15 GeV/c. These measurements provide a map of the bulk correlation structures in heavy-ion collisions. Contributions to these structures may come from jets, initial density fluctuations, elliptic flow, and/or momentum...

Two-particle correlation with the high-pT triggers allows the study of the hard scattering phenomena like soft QCD radiation [1, 2], angular ordering [3] or jet frag- mentation in the low and intermediate pT region [4, 5] where full jet reconstruction is challenging. An analysis of the first ALICE pp data where charged particle, π0 and isolated photon are used as trigger particles will be...

Non-statistical event-by-event fluctuations of the mean transverse momentum of charged particles in pp and Pb--Pb collisions are studied using the ALICE experiment at the LHC. The analysis is performed at $|\eta| < 0.8$ and $0.15 < p_{T} < 2 $~GeV/c. Multiplicity dependent results are obtained for pp collisions at $\sqrt{s}$~=~0.9, 2.76 and 7~TeV. Pb--Pb collisions at...

Event-by-event fluctuations of hadron ratios characterize the hadro-chemical composition of the hot and dense medium created in heavy-ion collisions. This makes the fluctuation signal sensitive to changes in the underlying structure of matter, and phase transition effects in particular. In the SPS energy range, inclusive hadronic observables indicate the onset of the deconfinement phase...

Correlations and fluctuations

The system created in a heavy ion collision in general is not azimuthally symmetri; moreover, the initial spatial distribution, e.g. that of the energy density, fluctuates event-by-event even at fixed impact parameter. Because of particle interactions, this initial spatial asymmetry leads to anisotropies in particle emission -- the phenomenon called anisotropic flow. The best known anisotropy...
