Quark polarization from parton scatterings in heavy ion collisions

Abstract Based on the result obtained in Ref. [J.-j. Zhang, R.-h. Fang, Q. Wang, X.-N. Wang, A microscopic description for polarization in particle scatterings, Phys. Rev. C100 (6) (2019) 064904. arXiv:1904.09152 , doi:10.1103/PhysRevC.100.064904 .], we calculate the polarization of quarks from parton scatterings in high energy heavy ion collisions. The result is compared with the STAR data at s N N = 200 GeV .
