Event-plane correlators

Understand

Correlators between event planes of different harmonics in relativistic heavy-ion collisions have the potential to provide crucial information on the initial state of the matter formed in these collisions.

• We present a new procedure for analyzing such correlators, which is less demanding in terms of detector acceptance than the one used recently by the ATLAS collaboration to measure various two-plane and three-plane correlators in Pb-Pb collisions at LHC.
• It can also be used unambiguously for quantitative comparison between theory and data.
• We use this procedure to carry out realistic simulations within the transport model AMPT.
