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.


报告人简介:Prof. Wang obtained Ph.D in particle and nuclear physics at Shandong University
in 1997. From February 2000 to May 2003, he was a Humboldt Fellow in the Institute for Theoretical
Physics, University of Frankfurt, Germany. From June 2003 and June 2005, he was a visiting professor in
the GSI Virtual Institute, a joint research program between the Institute of Theoretical Physics of University
of Frankfurt and the German National Laboratory for Heavy Ion Research. He was a senior research fellow
at Brookhaven National Lab in 2014. Since June 2005, Prof. Wang has been a professor at the Department
of Modern Physics, University of Science and Technology of China (USTC). In 2007 he was admitted to the
Hundred Talent program of CAS. Prof. Wang was awarded the Distinguished Young Scholars in 2012 by
National Science Foundation of China (NSFC). Prof. Wang's research field is theoretical high energy
nuclear physics. His research field is in application of quantum chromodynamics (QCD) in dense and hot
matter, quantum field theory at finite temperature and density, phenomenology of heavy ion collision, non-equilibrium dynamics in strong interaction matter.
