A systematic study of global spin polarizations and correlations of hadrons with different spins in relativistic heavy ion collisions

Ji-peng Lv, Zi-han Yu, Xiao-wen Li, Zuo-tang Liang

Abstract

Based on the formalism presented in [1], we make a systematic study of spin polarizations of hadrons with different spins including vector mesons, spin-1/2 and spin-3/2 hyperons and spin correlations of hadron-hadron such as hyperon-hyperon, hyperon-vector meson and vector meson-vector meson in relativistic heavy ion collisions. We present the results obtained and discuss the physical consequences in special cases. These results can be used for further numerical studies and for references of future experiments as well.
