Vorticity and Polarization
- Carlos Albert Salgado Lopez (Universidade de Santiago de Compostela (ES))
The hot and dense matter created in non-central heavy-ion collisions is supposed to have the initial angular momentum carried by two colliding nuclei. Some fraction of the angular momentum might be transferred to the global polarization of spin of particles composing the medium due to spin-orbit coupling. The STAR experiment has made the first observation of \Lambda hyperon polarization in...
The hydrodynamical model has by now become a paradigm for the study of the QCD plasma formed in nuclear collisions at ultra-relativistic energies. The possibility of new collective phenomena in heavy-ion collisions, such as vorticity and turbulence, have gained widespread attention in recent times. It was proposed that the rotation caused in the medium formed in non-central collisions may have...
