Dragos Velicanu (MIT)5/23/11, 3:00 PMCorrelations and fluctuationsParallelResults on two-particle angular correlations are presented in proton-proton collisions at center of mass energies of 0.9, 2.36, 2.76 and 7 TeV, over a broad range of pseudorapidity and azimuthal angle. In very high multiplicity events at 7 TeV, a pronounced structure emerges in the two-dimensional correlation function for particle pairs with intermediate $p_T$ of 1-3 GeV/c, in the kinematic...Go to contribution page

Ante Bilandzic (NIKHEF)5/23/11, 3:20 PMCorrelations and fluctuationsParallelAnte Bilandzic for the ALICE collaboration Measurements of anisotropic flow provided evidence for the creation of strongly interacting matter which appears to behave as an almost ideal fluid. Anisotropic flow signals the presence of multiple interactions and is very sensitive to the initial spatial anisotropy of the overlap region in non-central heavy-ion collisions. In this talk we report...Go to contribution page

Dr Yoshitaka Hatta (University of Tsukuba)5/23/11, 3:40 PMCorrelations and fluctuationsParallelIt has been argued that high-multiplicity proton-proton collisions at the LHC may exhibit collective phenomena usually studied in the context of heavy-ion collisions, such as elliptic flow. We study this issue using DIPSY, a brand-new Monte Carlo event generator which features almost-NLL BFKL dynamics and describes the transverse shape of the proton including all fluctuations. We predict the...Go to contribution page

Terence Tarnowsky (Michigan State University)5/23/11, 4:00 PMCorrelations and fluctuationsParallelTerence J Tarnowsky (for the STAR Collaboration) Dynamical fluctuations in global conserved quantities such as baryon number, strangeness, or charge may be observed near a QCD critical point. Results from new measurements of dynamical $K/\pi$, $p/\pi$, and $K/p$ ratio fluctuations are presented. The commencing of a QCD critical point search at RHIC has extended the reach of possible...Go to contribution page

Dr Jean-Yves Ollitrault (SPhT, Saclay)5/23/11, 4:20 PMPre-equilibrium and initial state physicsParallelLong-range azimuthal correlations are generated by fluctuations of the initial energy distribution, followed by collective flow. We list eight independent observables which can be measured using multiparticle azimuthal correlations in the first three Fourier harmonics. Some of these observables are already well known, such as $v_2\{2\}$ and $v_2\{4\}$, but most of them are new, in...Go to contribution page

Philippe Mota (Institut für Theoretische Physik, Goethe-Universität)5/23/11, 4:40 PMCorrelations and fluctuationsParallelWe investigate the effect of event-by-event fluctuations and the degree of granularity in the initial conditions on the collective evolution of matter created in heavy-ion collisions using fluid dynamics. Motivated by the glasma-flux-tube scenario, we model the initial condition by a set of randomly distributed longitudinal tubes in a boost-invariant 2D geometry. The model introduces two...Go to contribution page
