Abstract：
We present the preliminary results on the spin alignment matrix element ρ₀₀ for vector mesons K^*0(892) and φ(1020) in mid-central (20%—60%) Au+Au and p+p collisions at s_NN=200GeV. The values of ρ₀₀ with respect to reaction plane in Au+Au collisions are 0.36±0.02(stat)±0.13(sys) for K^*0(892) and 0.38±0.01 (stat)±0.04 (sys) for φ(1020). No evident global spin alignment with respect to reaction plane is observed in the measured p_T region up to 5GeV/c with current sensitivity. ρ₀₀ with respect to the production plane of the vector meson is also measured for K^*0(892) and φ(1020) in Au+Au collisions, and for φ(1020) in p+p collisions. No significant difference for the ρ₀₀ between Au+Au and p+p collisions is observed with our data sample.
