Local Spin Polarization in 200 GeV Au+Au and 2.76 TeV Pb+Pb Collisions

Abstract

We calculated the azimuthal angle dependence of the local spin polarization of hyperons in 200 GeV Au+Au and 2.76 TeV Pb+Pb collisions in the framework of the (3+1)D viscous hydrodynamic model CLVisc with AMPT initial conditions encoding initial orbital angular momenta. We find that the azimuthal angle dependence of the hyperon polarization strongly depends on the choice of the spin chemical potential ${\Omega }_{\mu \nu }$. With ${\Omega }_{\mu \nu }$ chosen to be proportional to the temperature vorticity, our simulation shows coincidental results with the recent measurements at RHIC.
