dc.description.abstract | We report the measurements of correlations between event-by-event fluctuations of amplitudes of
anisotropic flow harmonics in nucleus-nucleus collisions, obtained for the first time using a new analysis
method based on multiparticle cumulants in mixed harmonics. This novel method is robust against
systematic biases originating from nonflow effects and by construction any dependence on symmetry
planes is eliminated. We demonstrate that correlations of flow harmonics exhibit a better sensitivity to
medium properties than the individual flow harmonics. The new measurements are performed in Pb-Pb
collisions at the center-of-mass energy per nucleon pair of √=2.76 TeV
sNN p ¼ 2.76 TeV by the ALICE experiment at
the Large Hadron Collider. The centrality dependence of correlation between event-by-event fluctuations of
the elliptic v2 and quadrangular v4 flow harmonics, as well as of anticorrelation between v2 and triangular
v3 flow harmonics are presented. The results cover two different regimes of the initial state configurations:
geometry dominated (in midcentral collisions) and fluctuation dominated (in the most central collisions).
Comparisons are made to predictions from Monte Carlo Glauber, viscous hydrodynamics, AMPT, and
HIJING models. Together with the existing measurements of the individual flow harmonics the presented
results provide further constraints on the initial conditions and the transport properties of the system
produced in heavy-ion collisions. | |
