N2 - A measurement of the transverse polarization of the Λ and Λ̅ hyperons in pNe fixed-target collisions at √ sNN = 68.4 GeV is presented using data collected by the LHCb detector. The polarization is studied using the decay Λ → pπ− together with its charge conjugated process, the integrated values measured are PΛ = 0.029 ± 0.019(stat) ± 0.012(syst), PΛ̅ = 0.003 ± 0.023(stat) ± 0.014(syst). Furthermore, the results are shown as a function of the Feynman x variable, transverse momentum, pseudorapidity and rapidity of the hyperons, and are compared with previous measurements.
