DESCRIPTION:Speakers: Baochi  Fu (Peking University\, China)\nThe spin Hal
 l effect (SHE) is a generation of spin polarization for moving spin carrie
 rs in materials under an external electric field and has been observed in 
 semiconductors\, metals\, and insulators at or below room temperature. Rec
 ent theoretical analyses show that spin Hall current can be induced by the
  baryon chemical potential gradient which plays the role of the analogous 
 electric field and which becomes sizable in the fireballs created in heavy
 -ion collisions at beam energy of O(10) GeV. In this talk\, we focus on th
 is important mechanism and predict the signature of the SHE using a (3+1) 
 D viscous hydrodynamic model MUSIC with AMPT initial condition. We propose
  to use the second Fourier coefficients of the net spin polarization of La
 mbda hyperon as sensitive probes to search for the SHE. Those SHE observab
 les show a qualitative difference in both the sign and beam energy depende
 nce for the situations with and without the SHE. Future experimental obser
 vation of these distinct qualitative features would provide strong evidenc
 e for the existence of the SHE in the hot and dense QCD matter at trillion
 s of degrees.\n\nhttps://events.saifa.rs/event/554/contributions/386/
