DESCRIPTION:Speakers: Egor Alpatov (NRNU MEPhI)\nThe Quark-Gluon Plasma (Q
 GP)\, appearing in non-central nuclear-nuclear collisions is generated wit
 h large orbital angular momentum. Spin-orbit coupling alignes spin directi
 ons of produced particles with system angular momentum\, known as vorticit
 y. Properties of hyperon weak decays lead to the way of measuring polariza
 tion\, that reflects vorticity. The global polarization of $\\Lambda$ and 
 $\\overline\\Lambda$  hyperons was measured for Au+Au collisions at $\\sqr
 t{s_{NN}}$ = 7.7 - 200 GeV recorded with the STAR at the RHIC. However\, i
 t is also important to measure the global polarization of different partic
 le species. In this talk we will report new results of hyperon global pola
 rization ($P_{\\Lambda+\\overline\\Lambda}$ and $P_{\\Xi^{-}+\\overline\\X
 i^{+}}$) measurement via different methods for high-statistics Au+Au colli
 sions at $\\sqrt{s_{NN}}$ = 27 GeV.\n\nhttps://indico.particle.mephi.ru/ev
