| 英文摘要 | We report the transverse momentum (p(T)) and centrality dependence of global spin alignment (rho(00)) of K*(0) vector meson at midrapidity (vertical bar y vertical bar < 0.5) in Au + Au collisions at root s(NN) = 54.4 and 200 GeV with the STAR experiment at RHIC. The K*(0) results are compared to that of phi meson. At low-p(T) region and midcentral collisions, the K*(0) rho(00) is found to be smaller than 1/3 with about 4 sigma significance, while that of phi meson is observed to be larger than 1/3 with about 3 sigma significance. The rho(00) results are compared between RHIC and LHC energies. The physics implication of our results is also discussed. |
