T12.00001: Recent flow results from Heavy Ions Experiments at the LHC Invited Speaker: Andrew Adare An important role of the three largest experiments at the CERN Large Hadron Collider (ALICE, ATLAS, and CMS) is the exploration of strongly interacting nuclear matter at extreme temperature and density through heavy ion collisions. One of the most intriguing properties of the matter is its apparently fluidlike behavior. This anisotropic flow is inferred from studying the azimuthal distributions of emitted particles. The LHC heavy ion program has already proven tremendously successful after recording and analyzing a wealth of data from Pb-Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV in the Fall of 2010 and the Fall of 2011. I present recent results from the three experimental programs, with comparisons to measurements at lower collision energies and smaller system sizes as well as theoretical predictions to guide interpretation.

T12.00002: RHIC results on the energy dependence of flow fluctuations at all harmonics Invited Speaker: Paul Sorensen Recent theoretical and experimental studies have demonstrated that initial state geometry fluctuations can dominate two particle correlation measurements and flow fluctuations. In this talk, I will summarize some of the most convincing studies that have established this paradigm. Recent data sets gathered in the RHIC beam energy scan can be used to study these effects from energies below the expected threshold for QGP formation to well above the threshold. I'll review these measurements and discuss possible signatures for increases in the degrees of freedom at the boundary between a hadronic gas and QGP. [Preview Abstract] |

T12.00003: Characteristics of the strongly Interacting Quark Gluon Plasma -- implications of recent flow results Invited Speaker: Hannah Petersen Recent measurements of higher order flow coefficients offer a more complete understanding of how hot and dense QCD matter is created in relativistic heavy ion collisions and what its properties are. In addition to providing new constraints on the viscosity of the quark gluon plasma, anisotropic flow is sensitive to the structure of the initial state. As elliptic flow (v2) is generated by the difference in pressure gradients that result from the initial almond shape of the reaction region in non-central collisions, higher order coefficients encode more detailed information about the event-by-event fluctuating initial state profile. In my talk, I will present an overview of theoretical work aimed at understanding the correlations between initial state structures and final state correlations and their origin and discuss the current status of initial state models. I will outline how the new experimental findings at RHIC and LHC can be used towards characterize the dynamical evolution of relativistic heavy ion collisions with special emphasis on the role of event-by-event approaches and sophisticated multi-parameter fits to achieve this goal.
