Abstract
A measurement of the transverse polarization of the Λ and Λ 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),
PΛ = 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.
