Mapping the hydrodynamic response to the initial geometry in heavy-ion collisions
Fernando G. Gardim, Frederique Grassi, Matthew Luzum +1
We investigate how the initial geometry of a heavy-ion collision is transformed into final flow observables by solving event-by-event ideal hydrodynamics with realistic fluctuating…
Flow fluctuations and long-range correlations: elliptic flow and beyond
Matthew Luzum
These proceedings consist of a brief overview of the current understanding of collective behavior in relativistic heavy-ion collisions. In particular, recent progress in understand…
Understanding anisotropy generated by fluctuations in heavy-ion collisions
Rajeev S. Bhalerao, Matthew Luzum, Jean-Yves Ollitrault
Event-by-event fluctuations are central to the current understanding of ultrarelativistic heavy-ion collisions. In particular, fluctuations in the geometry of the early-time collis…
New flow observables
Rajeev S. Bhalerao, Matthew Luzum, Jean-Yves Ollitrault
Event-by-event fluctuations of the initial transverse density profile result in a collective flow pattern which also fluctuates event by event. We propose a number of new correlati…
Determining initial-state fluctuations from flow measurements in heavy-ion collisions
Rajeev S. Bhalerao, Matthew Luzum, Jean-Yves Ollitrault
We present a number of independent flow observables that can be measured using multiparticle azimuthal correlations in heavy-ion collisions. Some of these observables are already w…
Directed flow at mid-rapidity in event-by-event hydrodynamics
Fernando G. Gardim, Frederique Grassi, Yogiro Hama +2
Fluctuations in the initial geometry of a nucleus-nucleus collision have been recently shown to result in a new type of directed flow (v_1) that, unlike the usual directed flow, is…
