Anisotropic flow decorrelation in heavy-ion collisions with event-by-event viscous hydrodynamics

Decorrelation of the elliptic flow in rapidity is calculated within a hybrid approach which includes event-by-event viscous fluid dynamics and final state hadronic cascade model. The simulations are performed for Au+Au collisions at center-of-mass collision energies 27 200 GeV per nucleon pair, as well various colliding systems 72 pair. Initial conditions determined by an extended Monte Carlo Glauber model show better agreement with experimental data than initial from UrQMD transport We how observed decorrelation connected spatial anisotropies. also study effect increased cascade.
