摘要:
We investigate the azimuthal angle dependent local hydrodynamic helicity polarization of Λ hyperons, defined as the projection of the spin polarization vector along the directions of particle momenta, at BNL Relativistic Heavy Ion Collider beam energy scan energies by utilizing the relativistic ( 3+1 )D CLVisc hydrodynamics framework with SMASH initial conditions. As opposed to local spin polarization at high energy collisions, our hydrodynamic simulations demonstrate that the azimuthal angle dependent helicity polarization induced by the kine...
