Polarization of [lambda] ([lambda] [bar]) hyperons along the beam direction in Au+Au collisions at √sNN=200  GeV

The Λ (¯Λ) hyperon polarization along the beam direction has been measured in Au+Au collisions at √sNN=200 GeV, for the first time in heavy-ion collisions. The polarization dependence on the hyperons’ emission angle relative to the elliptic flow plane exhibits a second harmonic sine modulation, indi...
