Symmetry-plane correlations in flow analyses in ALICE — •Marcel Lesch for the ALICE collaboration — Technische Universität München, Germany

The study and experimental analysis of collective phenomena in heavy-ion collisions are nowadays to a great extent built on the so-called flow amplitudes vn and symmetry-planes Ψn. Both appear as two distinct degrees of freedom in the Fourier series expansion which is used to parametrize the distribution of azimuthal angles of produced particles in high-energy nuclear collisions. Using multiparticle correlation techniques, the studies of flow amplitudes vn and correlations amongst them have seen a lot of advancements over the past years.
In this talk, we address the complementary degrees of freedom by summarizing recent developments in the direction of symmetry-plane correlations (SPC) and the introduction of new observables for their measurement. We provide predictions of these observables for the initial coordinate space with the MC-Glauber model and for the final momentum space by iEBE-VISHNU for Pb–Pb collisions at √sNN =2.76   TeV. Finally, we present the first experimental results of SPC measured with these new observables using ALICE data for Pb–Pb at √sNN =2.76   TeV (2010).
