Toroidal vorticity explores the smallest droplets of fluid, focusing on a unique liquid feature potentially present in proton-nucleus (p+A) collisions. These experimental studies aim to uncover new insights into the behavior of matter under extreme conditions.

The Event Plane Detector, installed in the STAR experiment, enables precise determination of the event planes Ψ1 and Ψ2. This innovative tool enhances the study of anisotropic flow and collision dynamics in heavy-ion physics.

Particle correlations provide insights into the strong interactions between particles and the formation of resonances in heavy-ion collisions. These experimental measurements, conducted within the HADES collaboration, are particularly relevant for studies of the Equation of State of nuclear matter.
