Fluctuating initial conditions in hydrodynamics for two-particle correlations

Understand

Event-by-event hydrodynamics, with fluctuating initial conditions, has shown to nicely reproduce several features of experimentally observed quantities in high-energy nuclear collisions.

• Here we discuss how it may help to understand, in a unified way, the various structures observed in the long-range two-particle correlations, both in nucleus-nucleus and p-p collisions.
• Suggestions of how experimentally this description could be tested are also discussed.
