Abstract
We calculate the polarization of Lambda hyperons in Au-Au collisions at RHIC Beam Energy Scan in a state-of-the-art 3+1 dimensional cascade +viscous hydro model vHLLE+UrQMD. We find that the polarization of Lambdas in the out-of-plane direction decreases substantially with collision energy. We explore the connection between the polarization signal and thermal vorticity and discuss the feed-down and hadronic rescattering effects on the mean polarization of all produced Lambda hyperons.File | Dimensione | Formato | |
