Femto-cyclones and hyperon polarization in Heavy-Ion Collisions
arXiv:1507.04652 · doi:10.1103/PhysRevC.93.031902
Abstract
We study the structure of vorticity and hydrodynamic helicity fields in peripheral heavy-ion collisions using the kinetic Quark-Gluon String Model. The angular momentum conservation within this model holds with a good accuracy. We observe the formation of specific toroidal structures of vorticity field (vortex sheets). Their existence is mirrored in the polarization of hyperons of the percent order.
