Due to spin-orbit coupling, particles produced in such a system could become globally polarized along the direction of the system angular momentum. We present the results of Lambda and anti-Lambda hyperon global polarization measurements in Au+Au collisions at $\\sqrt{s_NN}$=62.4 GeV and 200 GeV performed with the STAR detector at RHIC. The observed global polarization of $\\Lambda$ and $\\overline{\\Lambda}$ hyperons in the STAR acceptance is consistent with zero within the precision of the measurements. The obtained upper limit, $|P_{\\Lambda,\\overline{\\Lambda}}|$ <= 0.02, is compared to the theoretical values discussed recently in the literature.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.98581.v2/t1","@type":"Dataset","description":"(Color online) Invariant mass distribution for the $\\Lambda$ (filled circles) and $\\overline{\\Lambda}$ (open squares) candidates after the quality cuts for...","name":"Figure 2"},{"@id":"https://doi.org/10.17182/hepdata.98581.v2/t2","@type":"Dataset","description":"(Color online) Global polarization of $\\Lambda$\u2013hyperons as a function of $\\Lambda$ transverse momentum $p^{\\Lambda}_{t}$.
