Global polarization of Anti-Lambda hyperon

Figures for the Anti-Lambda hyperon global polarization

Fig.1 Global polarization of Anti-Lambda hyperons as a function of Anti-Lambda transverse momentum.

Filled circles show the results for Au+Au collisions at sqrt{s_NN}=200 GeV (centrality region 20-70%) and open squares indicate the results for Au+Au collisions at sqrt{s_NN}=62 GeV (centrality region 0-80%).

Fig.2 Global polarization of Anti-Lambda hyperons as a function of Anti-Lambda pseudorapidity.

Filled circles show the results for Au+Au collisions at sqrt{s_NN}=200 GeV (centrality region 20-70%). A constant line fit to these data points yields P_Anti-Lambda = (1.8 +- 10.8)x10^{-3} with chi^2/ndf = 5.5/10. Open squares show the results for Au+Au collisions at sqrt{s_NN}=62 GeV (centrality region 0-80%). A constant line fit gives P_Anti-Lambda = (-17.6 +- 11.1)x10^{-3} with chi^2/ndf = 8.0/10.
