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 (√SNN)=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 pT region up to 5GeV/c with current sensitivity. p00 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.
