| Abstract | Global hyperon polarization, (P) over barH, in Au + Au collisions over a large range of collision energy, root S-NN, was recently measured and successfully reproduced by hydrodynamic and transport models with intense fluid vorticity of the quark-gluon plasma. While naive extrapolation of data trends suggests a large (P) over barH as the collision energy is reduced, the behavior of (P) over barH at small root S-NN < 7.7 GeV is unknown. Operating the STAR experiment in fixed-target mode, we measured the polarization of Lambda hyperons along the direction of global angular momentum in Au + Au collisions at root S-NN = 3 GeV. The observation of substantial polarization of 4.91 +/- 0.81(stat.) +/- 0.15(syst.)% in these collisions may require a reexamination of the viscosity of any fluid created in the collision, of the thermalization timescale of rotational modes, and of hadronic mechanisms to produce global polarization. |
