 Title: Study of strongly-coupled QCD matter with the ATLAS detector at the LHC

Speaker: Prof. Laszlo P. Csernai, University of Bergen, Norway and Wuhan University of Technology,China


 Abstract:
 With a Yang-Mills flux-tube initial state and a high-resolution (3+1)D
 particle-in-cell relativistic (PICR) hydrodynamics simulation, we
 calculated the Lambda polarization for different energies. The origin
 of polarization in high energy collisions is discussed, and we find
 linear impact parameter dependence of the global Lambda polarization.
 Furthermore, the global Lambda polarization in our model decreases
 very quickly as function of the beam energy, and the decline curve
 fits well the recent results of Beam Energy Scan (BES) program
 launched by the STAR Collaboration at the Relativistic Heavy Ion
 Collider (RHIC). The monemtum dependence, the otientation of
 polatization and its time evolution are discussed. Open questions
 today after QM 2018 are presented by the difference between the
 polatization of Lambda and anti-Lambda hyperons, and the symmetries of
 the beam directed polarization.
