  • I review recent measurements of a large set of flow observables associated with event-shape fluctuations and collective expansion in heavy ion collisions. First, these flow observables are classified and experiment methods are introduced. The experimental results for each type of observables are then presented and compared to theoretical calculations. A coherent picture of initial condition and collective flow based on linear and non-linear hydrodynamic responses is derived, which qualitatively describe most experimental results. I discuss new types of fluctuation measurements that can further our understanding of the event-shape fluctuations and collective expansion dynamics.
  • Using the AMPT model for relativistic heavy ion collisions, we have studied the di-hadron azimuthal angular correlations triggered by emitted jets in Au+Au collisions at center-of-mass energy {radical}(s{sub NN})=200 GeV and impact parameter b=8 fm. A double-peak structure for the associated particles at the away side of trigger particles is obtained after subtracting background correlations due to the elliptic flow. Both the near-side peak and the away-side double peaks in the azimuthal angular correlations are, however, significantly suppressed (enhanced) in events of small (large) triangular flow or triangularity in the initial collision geometry as a result of fluctuations. After subtractionmore » of background correlations due to the triangular flow, the away-side double peaks change into a single peak with broad shoulders on both sides. The away side of the di-hadron correlations becomes essentially a single peak after further subtraction of higher-order flows.« less

  • We investigate the sensitivity of [ital pionic] bounce-off and squeeze-out on the density and momentum dependence of the real part of the [ital nucleon] optical potential. For the in-plane pion bounce-off we find a strong sensitivity on both the density and momentum dependence whereas the out-of-plane pion squeeze-out shows a strong sensitivity only towards the momentum dependence but little sensitivity towards the density dependence. We observe strong differences between calculations including the [ital nucleon] optical potential and CASCADE calculations. The question of validity of the CASCADE approach in relativistic heavy-ion collisions can be resolved experimentally on the basis of themore » predicted pion nucleon correlations.« less
