Abstract: In the non-central collisions of heavy ions, two colliding nuclei carry a large angular momentum. After the collision, part of this angular momentum remains in the interaction zone and results in a vortical structure in the fluid. The vorticity of the fluid produces novel phenomena that are related to the non-trivial structure of Quantum Chromodynamics vacuum. To study these new phenomena, It is necessary to observe the vorticity of the fluid. Recently the Star collaboration at RHIC reported the vortical structure in the plasma of ...
