Abstract:
The main goal of heavy-ion collisions at (ultra)relativistic energies is to study a new phase of matter called Quark-Gluon Plasma (QGP), a deconfined system of quarks and gluons. A key observable used to characterize the properties of the QGP is the anisotropic flow. Strong fluctuations of the anisotropic flow allow an efficient selection of the events corresponding to a specific initial geometry. This technique, Event Shape Engineering, offers the possibility to study events with similar centralities, but different shapes. For those events, we present the anisotropic flow of inclusive and identified charged particles measured in Pb-Pb collisions at √sNN= 5.02$ TeV recorded by the ALICE detector. The measurements are presented for a wide range of particle transverse momenta within the pseudo-rapidity region |η|<0.8. These results provide strong constraints for initial conditions and transport coefficients of the QGP.
