报告简介👰🏽♀️🈳：Huge orbital angular momenta (OAM) are produced perpendicular to the reaction plane in non-central high energy heavy-ion collisions, and part of such huge OAM are transferred to the hot and dense matter created in collisions. Due to the shear of the longitudinal flow particles with spins can be polarized via the spin-orbit coupling in particle scatterings. Such a type of spin polarization with respect to the reaction plane is called the global polarization and is different from the particle's polarization with respect to the production plane which depends on the particle's momentum. The global spin polarization of Lambda and anti-Lambda has been measured by the STAR collaboration in Au+Au collisions at 7.7-200 GeV. Since then a lot of progress has been made in the field of global polarization. In this talk an overview will be given about recent experimental and theoretical progress in this and related field.
