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.
