Flow fluctuations and long-range correlations: elliptic flow and beyond
These proceedings consist of a brief overview of the current understanding of
collective behavior in relativistic heavy-ion collisions. In particular, recent
progress in understanding the implications of event-by-event fluctuations have
solved important puzzles in existing data -- the "ridge" and "shoulder"
phenomena of long-range two-particle correlations -- and have created an
exciting opportunity to tightly constrain theoretical models with many new
observables.Comment: 10 pages, 2 figures, Proceedings for the 22nd International

Anisotropic flow of charged particles at TeV measured with the ALICE detector
Measurements of anisotropic flow in heavy-ion collisions provide 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 article we report
measurements of elliptic , triangular , quadrangular and
pentagonal flow. These measurements have been performed with 2- and
multi-particle correlation techniques.Comment: 4 pages, 4 figures, Quark Matter 2011 proceeding
