Michael Strickland (Kent State University)29/09/2015, 10:50Collective DynamicsContributed talkWe derive the equations of motion for a system undergoing boost-invariant longitudinal and azimuthally-symmetric transverse "Gubser flow" using leading-order anisotropic hydrodynamics. This is accomplished by assuming that the one-particle distribution function is ellipsoidally-symmetric in the momenta conjugate to the de Sitter coordinates used to parameterize the Gubser flow. We then...Go to contribution page

LongGang Pang (Lawrence Berkeley National Laboratory)29/09/2015, 11:10Collective DynamicsContributed talkThe decorrelation of 2nd and 3rd order anisotropic flow along longitudinal direction with large pseudorapidity η gap is investigated in event-by-event (3+1)D ideal hydrodynamics with fluctuating initial conditions from A MultiPhase Transport (AMPT) model. The agreement between our results and CMS data for all available centralities in Pb+Pb collisions at LHC suggests that the string...Go to contribution page

Koichi Murase (The University of Tokyo)29/09/2015, 11:30Collective DynamicsContributed talkThermal fluctuations arising during hydrodynamic evolution of the system (a.k.a., *hydrodynamic fluctuations*) [1] play an important role in event-by-event hydrodynamic simulations. For example, entropy production fluctuates during the expansion even if we start from a common initial condition in a macroscopic sense [2]. On the other hand, the effect of the fluctuations must be...Go to contribution page

Chris Flores29/09/2015, 11:50Collective DynamicsContributed talkThe Beam Energy Scan (BES) at the Relativistic Heavy-Ion Collider was proposed to characterize the properties of the medium produced in heavy-ion interactions over a broad range of baryon chemical potential. The aptitude of the STAR detector for mid-rapidity measurements has previously been leveraged to measure identified particle yields and spectra to extract bulk properties for the BES...Go to contribution page

Maxime Guilbaud (Rice University (US))29/09/2015, 12:10Collective DynamicsContributed talkMost studies of anisotropy flow phenomena have assumed a global flow phase angle (or event plane angle) that is boost invariant in pseudorapidity ($\eta$). It was realized in recent years that this assumption may not be valid in presence of initial-state fluctuations, especially along the longitudinal direction. The effect of eta-dependent event plane fluctuations would break the factorization...Go to contribution page
