Collective flow in a hot, dense, and strongly interacting medium — •Björn Schenke — Physics Department, Brookhaven National Laboratory, Upton, NY 11973, USA
The large collective flow measured at the Relativistic Heavy-Ion Collider at Brookhaven National Laboratory and the Large Hadron Collider at CERN is one of the most striking observations in heavy-ion experiments. This anisotropy of particle production in the plane transverse to the collision axis is interpreted as the fluid-dynamic response of the created strongly interacting matter to the initial collision geometry, which fluctuates event by event. I review recent developments in the theoretical description of the bulk dynamics of heavy-ion collisions with focus on viscous fluid-dynamics and models for the initial state and its fluctuations. Recent progress using a combined Yang-Mills and viscous fluid-dynamic framework has lead to great successes in describing a wide range of experimental data, leading to the unprecedented opportunity to extract quantitative information on the transport properties of the created quark-gluon plasma, such as its shear viscosity. This demonstrates how heavy-ion collisions can be used to study fundamental properties of quantum-chromo-dynamics.
